# Simulation with Verilator
|
|
|
|
Different executables will be built for different architecture configurations, e.g., rv64gc, rv32i. A executable can run all the test suites that it can run with `+TEST=<testsuite>`.
|
|
|
|
Demand:
|
|
|
|
- Avoid unnecessary compilation by sharing the same executable for a specific configuration
|
|
- executables are stored in `obj_dir_non_profiling` and `obj_dir_profiling` correspondingly
|
|
- Wsim should support `-s verilator` option and run simulation with Verilator.
|
|
|
|
## Folder Structure
|
|
|
|
This folder contains the following files that help the simulation of Wally with Verilator:
|
|
|
|
- Makefile: simplify the usage with Verialtor
|
|
- executables
|
|
- `obj_dir_non_profiling`: non-profiling executables for different configurations
|
|
- `obj_dir_profiling`: profiling executables for different configurations
|
|
- logs in `logs` and `logs_profiling` correspondingly
|
|
- [NOT WORKING] `logs`: contains all the logs
|
|
|
|
## Examples
|
|
|
|
```shell
|
|
# non-profiling mode
|
|
make WALLYCONF=rv64gc TEST=arch64i run
|
|
# profiling mode
|
|
make WALLYCONF=rv64gc TEST=arch64i profile
|
|
|
|
# remove all the temporary files, including executables and logs
|
|
make clean
|
|
``` |
