Скачать или смотреть How to Implement Any Truth Table on FPGA (UDPs in Verilog) | 100 Days of FPGA

In this video (Day 7 of the 100 Days of FPGA series), I explain User Defined Primitives (UDPs) in Verilog and why they are not synthesizable for FPGA implementation. Then, I show how we can achieve the same functionality using case statements, which are synthesizable.

I start by showing how to derive a Boolean expression from a truth table using a K-map and directly write that expression in Vivado. Then, I demonstrate how you can use a User Defined Primitive to describe the entire truth table without simplifying it manually. Finally, I explain that since UDPs can’t be synthesized on an FPGA, we use case statements to implement any truth table directly on hardware.

By the end of this video, you’ll understand how to implement any Boolean function on FPGA from its truth table — even without finding the equation manually!


You'll learn:

• Why UDPs are great for simulation but fail synthesis (and why that matters for your FPGA!).

• The secret alternative: Using a synthesizable case statement to easily map your truth table inputs to outputs, achieving the same behavior in hardware.

• A quick look at using K-Maps vs. the UDP method to save time in the design process.
