Hi,

that will depend on your 8032 core is and how much ROM and RAM you'll need.

I have used the 8052 core from OpenCore's T51 project. The original core took a huge amount of resources, due to the way IRAM and ROM were implemented.

With a couple of modifications, I managed to reduce it to some 8K LEs.

The design also has some 16KB ROM and 4KB XRAM, all implemented in the FPGAs M9K blocks.

This, plus a bunch of peripherals, all fit in a EP2C20.

As for tools, you'll need

a) a 8051 compiler, libraries, etc. sdcc is pretty decent.

b) a 8051 emulator to debug your sofware.

c) ModelSim to simulate your complete design.

In any case, unless you have a really good reason not to, I suggest you use the NIOS II processor.

Compared to the free 8051 cores I've seen:

- NIOS II/e is also free.

- NIOS II/e takes much less resources.

- NIOS II is faster, even /e.

- There are much better tools for development and debugging.
