asfpga v1.00e

Description:

asfpga is an assembler written for use in FPGA design. It can be easily modified for your instruction set. The ultimate goal of this software is to allow a FPGA designer to easily write assembly code for a custom instruction set.

The current version allows to create a listing file, a memory dump file which can be used in debugging HDL code using $readmemh() or equivalent routine, and a binary file which can be used to program a EPROM.

Howto compile and use:

To compile:

gcc -o asfpga main.c asfpga.c error.c

To use:

./asfpga inputfileName.asm

 * Comments should be preceded by a ';'.
 * All labels should be preceded by a '#'
 * Empty lines in the source code are not allowed => should (put ';' to indicate a carriage return)
 * Instructions such as 'LDI M, LED2', should have a space after comma
 * All characters *must* be upper case => turn CAPS on while coding :-)
