I finally got the LM32 compiled and synthesized for my altera board (by hand not using MiSoC/MiGen) but I couldn't get anything working (even a simple gpio pin toggle). So, I simulated them both in Modelsim. I found something weird on the memory contents of the Altera vs Xilinx.
The xilinx build uses a coe file converted from hex for the memory for startup but altera quartus uses a hex file. When I simulated, I found the memory contents inserting some weird strings of 0x0000000 in between successive words in the altera simulation but not in the xilinx simulation. I suspect this is happening in the hardware also and hence nothing is happening with the gpio. Do most on this list use Icarus verilog? I could try that but I am not sure it allows you to view memory contents...any clues on why this could be happening?
