I'd think that time is more important than coverage at this stage, so if you can set up a number of tests with enough coverage that would only take a few hours, you could go for that. When you get a faster model, or an FPGA materialises you increase the number of tests, and so on, up to the full test-suite. At least that would keep the "don't break" status because you could fix and test quickly afterwards... cheers, --renato
