We have a design with an embedded arm processor. We can do software-hardware co-sim and run simple c test code on arm processor. But we’d like to have another way which we can bypass (sort of disconnect) arm processor and use a TB BFM to drive AHB bus. Note we don’t want to touch rtl code.…[Read more]

It takes time to recompile. So is it possible to run multiple RTL test cases out of the same modelsim work library? Actually is it the way how we setup multiple test cases environment since we don’t want to compile all rtl+tb per each test case?

siro s1 (nrst, osc);

assign trig_en = a1 ^ a2;
assign clk = trig_en & osc;
assign a1 = ~(nrst & clk_div2);
