VHDL is a huge language, and LogicWorks does not attempt to provide a full implementation in this version. VHDL has become the industry standard method for describing digital systems in a high-level language, and an understanding of it is now essential for any working circuit designer.

LogicWorks was created with the following goals in mind: to give the student an introduction to the concepts and practicalities of using CAD tools to provide a "virtual workbench" that allows the student to quickly test out circuit design ideas and document results to be intuitive and easy to use, so that time is not wasted on the details of installing and operating the software to provide the features and interfaces necessary to work with current design technologies to provide an upward path to professional design tools used in industry.The major change in LogicWorks 5 from previous versions is the addition of VHDL simulation. In light of this situation, we developed LogicWorks, the student version of DesignWorks, to be used by students in lab settings and by instructors as an interactive teaching aid. Many instructors want to give their students hands-on experience with CAD tools used in industry, but the high cost and complexity of most commercial CAD programs limit their use at academic institutions. At Capilano Computing Systems Ltd., our flagship product, DesignWorks, is used in government, industrial, and academic labs worldwide, providing users with speed, ease of use, and affordability. Powerful computer-aided design (CAD) programs have been commercially developed to meet the increasing demands facing industry. It is no longer possible for an individual engineer or a corporation to remain competitive while using pencil and paper for design. As electronic systems have become more complex, operating speeds higher, and custom chip technology more widespread, software tools for engineers have become an essential part of the design process. Now, you know how combinational logic works in FPGA and with my previous article on DFF you now know the two most important piece of circuitry in your FPGA.Welcome to LogicWorks and the world of interactive circuit design.

Xilinx also give you coding style advice next to the architecture presentation so you can take advantage of the full potential of their FPGA. When you work on FPGA, it is always good to know what architecture the constructor have chosen. For example, the Xilinx 7 serie got 6-LUT that can be configured as two 5-LUT as long as the 5 variables are the same, whereas the Altera ones got 8-LUT that can be configured as a 3-LUT + a 5-LUT (and many other configurations). The number of inputs and outputs of a LUT can vary depending on the constructor and the version of your FPGA. Most devices included with LogicWorks default to a delay of 1 ns (nano second, or 10-9 seconds). LogicWorks uses integers to represent simulated time values. And with a N-LUT, any equation with N variables.įPGA contains thousands of LUTs that will allow you to implement very complex designs. Add a pull-up resistor (using the Resistor and +5V symbols) and an inverter (NOT in the Simulation library), and wire them as shown above.

With a 2-LUT you can reproduce all the gates described above. You see ? We only need to change the SRAM value to change the operation. Notice the little circle at the end of the triangle ? This is the symbol of “not” you will find it in NAND, NOR, XNOR too. Yes, the three missing gates are the NAND, the NOR and the XNOR which are just the three above with and inverters on the output. – Wait ! I heard there are seven logic gates. The output is 1 if and only if one of the inputs is 1 (the other one must be 0) The output is a 1, if at least one of the two input bits is 1. The output is a 1, if and only if both input bits are 1.

If it’s a 0, it becomes a 1.įor a gate with two inputs bit and only one output bit, we can use:

Today it’s time to study how to manipulate those data. In a previous article about DFF, we saw how to store data in our FPGA. And it’s a huge part of how FPGA does it. Of course combinational logic and LUTs aren’t the only way to process a signal in electronic, but it’s a tiny part that could have satisfied my curiosity back then. Because today is the day we speak about combinational logic and LUTs. If you asked yourself this question, you’re in the right place. And I couldn’t stop asking myself, “how can we do anything with only 0 and 1?” I wondered what were all those cables and what were their purposes.
