Eclipse Webmaster requested to merge github/fork/zchamski/pr/spike-limit-2M-steps into cva6/dev Jun 01, 2023

Created by: zchamski

In order to prevent runaway executions of Spike, this PR sets an execution limit of 2 million cycles on all Spike executions triggered by the CVA6 DV scripts. The mechanism used is the new Spike cmdline option introduced in PR #1949.

Sullary of file changes:

cva/sim/Makefile (spike_stepout): Set up Spike stepout option if caller supplied a step count limit. (spike): Invoke Spike with a 'stepout' limit option (possibly empty).
cva6/sim/cva6.yaml (iss: spike): Set step limit of Spike runs to 2M. Add explanatory comments.

Set Spike execution limit to 2M steps across all verification runs.
