### Simulating it
|

|
|
|
Both Verilator and Icarus Verilog can be used for simulation. You can select which one you want with the SIM variable on [common.mk](./common.mk)

|
Specifically this list shows the software needed and the versions used during development (other versions should work as well)

|
|
|
|
2023-03-06 21:57:36 +00:00
|
|
|
* Icarus Verilog : version 11.0 OR **(preferred)** Verilator : 5.006
|
2023-03-05 06:37:07 +00:00
|
|
|
* bin86 : 0.16.21
|
|
|
|
|
* GNU Make : 4.4.1
|
|
|
|
|
* xxd : 2022-01-14
|
2023-03-06 21:57:36 +00:00
|
|
|
* POSIX coreutils : GNU coreutils 9.1

|
2023-03-05 06:37:07 +00:00
|
|
|
After that you can run `make` on the top level directory and it should build everything and start the simulation
