anyone have ROM design code in VERILOG..... All 16 input values are specified, so the example will work fine without a default case. However, I usually include "default: DATA = 4'bxxxx;" to help catch other bugs during simulation (such as ADDR undefined). Verilog It can be simulated but it will have nothing to do with hardware, i.e. it won’t synthesize. We don’t spend much time on Behavioral Verilog because it is not a particularly good language and isn’t useful for hardware synthesis.

I'm new with verilog and I'm suppose to create a 64x8 memory unit in verilog with a 16x4 SRAM. I designed it but I don't know how to interpret it into verilog. I do have the 16x4 SRAM and the 2 to 4 decoder but from my understanding is that I need to create a 64x8 which I'm not sure how. Here are my 2 modules I have so far. The CPU testbench simulates a block of ROM, which is loaded from a separate le. This makes it very easy to write additional test vectors and to copy the test code into the physical EEPROM. Likewise, the control module test consists of a short segment of erilogV code coupled with an easy-to-read text le containing the test process.

To convert the assembly code into binary that can be read by the behavioral memory, you need to run the make test.pl script2 which is included in the tests directory. This will output a hexidecimal word, one per line, for each instruction in the program. The script will also output the halt instruction as … CSE 322 mips-verilog.1 Kogge, ND, 12/5/2007 3/7/08 An Example Verilog Structural Design: An 8-bit MIPS Processor Peter M.
