Building Libraries for OrCAD Just Got a Whole Lot Easier (Hint: We built them for you)
As you are probably already aware—a lot goes into designing a printed circuit board. From routing to part selection, signal quality, and manufacturability, you have a lot to evaluate. With everything there is to consider, why are you still spending valuable time building symbols and footprints for your designs? On average, it takes between 8-16 hours for an engineer to build one high pin count symbol and footprint. This time could be better spent focusing on your design instead of building parts for it. Ultra Librarian® eliminates the need to build libraries by providing access to a cloud-based database of over 9 million pre-built schematic symbols, PCB footprints, and 3D models directly inside the OrCAD™ environment. Search, preview, and place parts inside OrCAD Capture without ever having to leave the OrCAD environment. All the parts in the Ultra Librarian database have been built to IPC and ANSI standards, and are automatically linked unifying the elements of the part as a single component with multiple views for logical, physical, and 3D. You can now move from schematic capture to PCB layout seamlessly without having to worry the parts you use will not line up in the end. Seamless Integration In the past, PCB design engineers have been forced to leave their native CAD environment to search for parts or build parts themselves. Pre-built parts found on open source websites can be error prone, and are not always built to industry standards. With Ultra Librarian’s seamless integration inside OrCAD Capture, you no longer need to leave your design environment to find the parts you need for your design. Gain instant access to Ultra Librarian’s growing cloud-based library for millions of pre-built components. are search for parts, preview the symbols, footprints, and 3D models, and place directly into your schematic without ever leaving the design environment. Unified Library of Components How many times have you worked on a design where three different people created the symbol, footprint, and 3D model—and of course they don’t match? If all the parts are sourced separately or built at different times, they may not be in sync which can lead to miscommunication and design errors. Finding the correct combinations is yet another challenge left to the design team. Ultra Librarian for OrCAD provides a unified library solution for your PCB symbols, footprints, and 3D model needs. All three are automatically linked, unifying the elements of the part as a single component with multiple views for logical, physical, and 3D. The symbols found in the Ultra Librarian database have properties associated with them that allow you to move seamlessly from schematic capture to PCB layout, where the footprints are arranged on the board for connectivity, and finally to step models defining the size and shape of the part that sits on the footprint. Parts Built to Standards Standards are an increasingly important aspect to obtaining pre-built parts for your PCB design process. If parts are not built to industry standards they may not be very useful to you. Ultra Librarian has developed a rigorous building and testing process to ensure that all the parts found in the Ultra Librarian for OrCAD portal are built with industry standards including IPC and ANSI. All symbols in the library have been built to ANSI Y32.2-1975 (reaffirmed 1989) standard to ensure reliability through your schematic. Footprints have been built to IPC-7351B standards where possible and 3D models are rendered from footprint data and match the footprints’ exact size, rotation, and orientation. As a standards-based library, you know when you place apart from Ultra Librarian for OrCAD into your design, the part will fit and function properly. Stop Wasting Time Building Parts and Start Creating Innovative Products Ultra Librarian for OrCAD provides access to the most robust library of pre-built PCB parts on the market today. This type of in-software access guarantees engineers will save time, reduce errors, and ensure consistency across their PCB part libraries. Finding and utilizing library components is now a natural part of the design process. Save time, avoid errors, and focus on design with Ultra Librarian for OrCAD.

7-segment Display and Driving a 7-segment Display
The emission of photons from a 7-segment display occurs when the diode junction of each segment is forward biased by an external voltage allowing current to flow across its junction, and in Electronics we call this process electroluminescence.
The actual colour of the visible light emitted by an LED, ranging from blue to red to orange, is decided by the spectral wavelength of the emitted light which itself is dependent upon the mixture of the various impurities added to the semiconductor materials used to produce it.
7-segment Display
Light emitting diodes have many advantages over traditional bulbs and lamps, with the main ones being their small size, long life, various colours, cheapness and are readily available, as well as being easy to interface with various other electronic components and digital circuits.
But the main advantage of light emitting diodes is that because of their small die size, several of them can be connected together within one small and compact package producing what is generally called a 7-segment Display.
The 7-segment display, also written as “seven segment display”, consists of seven LEDs (hence its name) arranged in a rectangular fashion as shown. Each of the seven LEDs is called a segment because when illuminated the segment forms part of a numerical digit (both Decimal and Hex) to be displayed.
An additional 8th LED is sometimes used within the same package thus allowing the indication of a decimal point, (DP) when two or more 7-segment displays are connected together to display numbers greater than ten.
Each one of the seven LEDs in the display is given a positional segment with one of its connection pins being brought straight out of the rectangular plastic package. These individually LED pins are labelled from a through to g representing each individual LED. The other LED pins are connected together and wired to form a common pin.
So by forward biasing the appropriate pins of the LED segments in a particular order, some segments will be light and others will be dark allowing the desired character pattern of the number to be generated on the display. This then allows us to display each of the ten decimal digits 0 through to 9 on the same 7-segment display.
The displays common pin is generally used to identify which type of 7-segment display it is. As each LED has two connecting pins, one called the “Anode” and the other called the “Cathode”, there are therefore two types of LED 7-segment display called: Common Cathode (CC) and Common Anode (CA).
The difference between the two displays, as their name suggests, is that the common cathode has all the cathodes of the 7-segments connected directly together and the common anode has all the anodes of the 7-segments connected together and is illuminated as follows.
1. The Common Cathode (CC) – In the common cathode display, all the cathode connections of the LED segments are joined together to logic “0” or ground. The individual segments are illuminated by application of a “HIGH”, or logic “1” signal via a current limiting resistor to forward bias the individual Anode terminals (a-g).
Common Cathode Configuration
2. The Common Anode (CA) – In the common anode display, all the anode connections of the LED segments are joined together to logic “1”. The individual segments are illuminated by applying a ground, logic “0” or “LOW” signal via a suitable current limiting resistor to the Cathode of the particular segment (a-g).
Common Anode Configuration
In general, common anode displays are more popular as many logic circuits can sink more current than they can source. Also note that a common cathode display is not a direct replacement in a circuit for a common anode display and vice versa, as it is the same as connecting the LEDs in reverse, and hence light emission will not take place.
Depending upon the decimal digit to be displayed, the particular set of LEDs is forward biased. For instance, to display the numerical digit 0, we will need to light up six of the LED segments corresponding to a, b, c, d, e and f. Thus the various digits from 0 through 9 can be displayed using a 7-segment display as shown.
Digital Segments for all Numbers
Then for a 7-segment display, we can produce a truth table giving the individual segments that need to be illuminated in order to produce the required decimal digit from 0 through 9 as shown below.
7-segment Display Truth Table
Decimal
Digit Individual Segments Illuminated a b c d e f g 0 × × × × × × 1 × × 2 × × × × × 3 × × × × × 4 × × × × 5 × × × × × 6 × × × × × × 7 × × × 8 × × × × × × × 9 × × × × ×
Driving a 7-segment Display
Although a 7-segment display can be thought of as a single display, it is still seven individual LEDs within a single package and as such these LEDs need protection from over current. LEDs produce light only when it is forward biased with the amount of light emitted being proportional to the forward current.
This means then that an LEDs light intensity increases in an approximately linear manner with an increasing current. So this forward current must be controlled and limited to a safe value by an external resistor to prevent damage to the LED segments.
The forward voltage drop across a red LED segment is very low at about 2-to-2.2 volts, (blue and white LEDs can be as high as 3.6 volts) so to illuminate correctly, the LED segments should be connected to a voltage source in excess of this forward voltage value with a series resistance used to limit the forward current to a desirable value.
Typically for a standard red coloured 7-segment display, each LED segment can draw about 15 mA to illuminated correctly, so on a 5 volt digital logic circuit, the value of the current limiting resistor would be about 200Ω (5v – 2v)/15mA, or 220Ω to the nearest higher preferred value.
So to understand how the segments of the display are connected to a 220Ω current limiting resistor consider the circuit below.
Driving a 7-segment Display
In this example, the segments of a common anode display are illuminated using the switches. If switch a is closed, current will flow through the “a” segment of the LED to the current limiting resistor connected to pin a and to 0 volts, making the circuit. Then only segment a will be illuminated. So a LOW condition (switch to ground) is required to activate the LED segments on this common anode display.
But suppose we want the decimal number “4” to illuminate on the display. Then switches b, c, f and g would be closed to light the corresponding LED segments. Likewise for a decimal number “7”, switches a, b, c would be closed. But illuminating 7-segment displays using individual switches is not very practical.
7-segment Displays are usually driven by a special type of integrated circuit (IC) commonly known as a 7-segment decoder/driver, such as the CMOS 4511. This 7-segment display driver which is known as a Binary Coded Decimal or BCD to 7-segment display decoder and driver, is able to illuminate both common anode or common cathode displays. But there are many other single and dual display drivers available such as the very popular TTL 7447.
This BCD-to-7 segment decoder/driver takes a four-bit BCD input labelled A, B, C and D for the digits of the binary weighting of 1, 2, 4 and 8 respectively, has seven outputs that will pass current through the appropriate segments to display the decimal digit of the numeric LED display.
The digital outputs of the CD4511 are different from the usual CMOS outputs because they can provide up to 25mA of current each to drive the LED segments directly allowing different coloured LED displays to be used and driven.
Using a 4511 Driver
In this simple circuit, each anode terminal of the common cathode LED display is connected directly to the 4511 decoder/driver via a current limiting resistor. The cathodes of each LED segment are internally connected to ground. The binary inputs, A, B, C, and D to the 4511 are via four mechanical ON/OFF switches. When all the switches are in the open position, the voltage across the four 1kΩ resistors is zero (0V) as they are tied directly to ground. This prevents any false triggering of the display when any of the switches are open.
Then we can see that using a BCD to 7-segment display driver such as the CMOS 4511 or TTL 7447, we can control the LED display using just four switches (instead of the previous 8) or a 4-bit binary signal allowing up to 16 different combinations.
Most digital equipment use 7-segment Displays for converting digital signals into a form that can be displayed and understood by the user. This information is often numerical data in the form of numbers, characters and symbols. Common anode and common cathode seven-segment displays produce the required number by illuminating the individual segments in various combinations.
LED based 7-segment displays are very popular amongst Electronics hobbyists as they are easy to use and easy to understand. In most practical applications, 7-segment displays are driven by a suitable decoder/driver IC such as the CMOS 4511 or TTL 7447 from a 4-bit BCD input. Today, LED based 7-segment displays have been largely replaced by liquid crystal displays (LCDs) which consume less current.

Building Libraries for OrCAD Just Got a Whole Lot Easier (Hint: We built them for you)
As you are probably already aware—a lot goes into designing a printed circuit board. From routing to part selection, signal quality, and manufacturability, you have a lot to evaluate. With everything there is to consider, why are you still spending valuable time building symbols and footprints for your designs? On average, it takes between 8-16 hours for an engineer to build one high pin count symbol and footprint. This time could be better spent focusing on your design instead of building parts for it. Ultra Librarian® eliminates the need to build libraries by providing access to a cloud-based database of over 9 million pre-built schematic symbols, PCB footprints, and 3D models directly inside the OrCAD™ environment. Search, preview, and place parts inside OrCAD Capture without ever having to leave the OrCAD environment. All the parts in the Ultra Librarian database have been built to IPC and ANSI standards, and are automatically linked unifying the elements of the part as a single component with multiple views for logical, physical, and 3D. You can now move from schematic capture to PCB layout seamlessly without having to worry the parts you use will not line up in the end. Seamless Integration In the past, PCB design engineers have been forced to leave their native CAD environment to search for parts or build parts themselves. Pre-built parts found on open source websites can be error prone, and are not always built to industry standards. With Ultra Librarian’s seamless integration inside OrCAD Capture, you no longer need to leave your design environment to find the parts you need for your design. Gain instant access to Ultra Librarian’s growing cloud-based library for millions of pre-built components. are search for parts, preview the symbols, footprints, and 3D models, and place directly into your schematic without ever leaving the design environment. Unified Library of Components How many times have you worked on a design where three different people created the symbol, footprint, and 3D model—and of course they don’t match? If all the parts are sourced separately or built at different times, they may not be in sync which can lead to miscommunication and design errors. Finding the correct combinations is yet another challenge left to the design team. Ultra Librarian for OrCAD provides a unified library solution for your PCB symbols, footprints, and 3D model needs. All three are automatically linked, unifying the elements of the part as a single component with multiple views for logical, physical, and 3D. The symbols found in the Ultra Librarian database have properties associated with them that allow you to move seamlessly from schematic capture to PCB layout, where the footprints are arranged on the board for connectivity, and finally to step models defining the size and shape of the part that sits on the footprint. Parts Built to Standards Standards are an increasingly important aspect to obtaining pre-built parts for your PCB design process. If parts are not built to industry standards they may not be very useful to you. Ultra Librarian has developed a rigorous building and testing process to ensure that all the parts found in the Ultra Librarian for OrCAD portal are built with industry standards including IPC and ANSI. All symbols in the library have been built to ANSI Y32.2-1975 (reaffirmed 1989) standard to ensure reliability through your schematic. Footprints have been built to IPC-7351B standards where possible and 3D models are rendered from footprint data and match the footprints’ exact size, rotation, and orientation. As a standards-based library, you know when you place apart from Ultra Librarian for OrCAD into your design, the part will fit and function properly. Stop Wasting Time Building Parts and Start Creating Innovative Products Ultra Librarian for OrCAD provides access to the most robust library of pre-built PCB parts on the market today. This type of in-software access guarantees engineers will save time, reduce errors, and ensure consistency across their PCB part libraries. Finding and utilizing library components is now a natural part of the design process. Save time, avoid errors, and focus on design with Ultra Librarian for OrCAD.
