Welcome to my ongoing series covering mathematics and algorithms with FPGAs. This series begins with the basics of Verilog numbers, then considers fixed-point, division, square roots and CORDIC before covering more complex algorithms, such as data compression.| Project F
Hardware design can be unforgiving, so it pays to use any advantage you can get. Verilator is a Verilog simulator and C++ compiler that also supports linting: statically analysing your designs for issues. Not only can Verilator spot problems your synthesis tool might overlook, but it also runs quickly.| Project F
Welcome back to Exploring FPGA Graphics. Last time, we raced the beam; this time, we’ll recreate the arcade classic, Pong and play against our FPGA.| Project F
It’s common for a simulation or firmware to need data loading into a memory array, ram, or rom. Fortunately, Verilog provides the $readmemh and $readmemb functions for this very purpose. Unfortunately, there is a dearth of good Verilog documentation online, so using them can be harder than it should be. This how to explains the syntax and provides plenty of examples, including how to do this in Yosys and Xilinx Vivado.| Project F
