asfpga is a specialized assembler designed for FPGA design. It is a software tool that helps developers to write code in a specific format that is compatible with programmable logic chips. Its main purpose is to assist in the development of efficient and optimized FPGA designs.
The current version of ASFPGA provides several essential features, including creating a listing file, a memory dump file that assists in debugging HDL code using $readmemh() or equivalent routine, and a binary file that can program an EPROM.
To compile ASFPGA, you can follow a simple process: gcc -o asfpga main.c asfpga.c error.c. Meanwhile, to use it, run ./asfpga inputfileName.asm. Some tips to bear in mind include using ‘;’ to indicate a carriage return, preceding comments with a ‘;’, and preceding all labels with a ‘#’. It's essential to note that empty lines in the source code are not allowed. Instead, use ‘;’ to indicate their absence.
Additionally, instructions, such as 'LDI M, LED2' should have a space after the comma, and all characters should be in upper case. Therefore, it's advisable to turn on CAPS Lock while coding with ASFPGA.
In conclusion, ASFPGA is an impressive software with many benefits for FPGA designers. Its user-friendly interface, easy modifiability, and numerous features make it a must-have tool for FPGA development.
