In Modelsim, you can use cursors to do that. Using an if statement without an else clause in a modelsim count transitions "combinational process" can result in latches being inferred, unless all signals driven by the process are given unconditional default assignments.
So, transitions between states seems to be really well, bu the problem now is, taht the output DIR_SIGNAL modelsim count transitions doesn&39;t change and during whole simulation is on the same level. This command is an HDL Verifier extension to the ModelSim command set. See more results. When reset, the state machine starts from the state &39; init &39; in which it&39;ll wait until it reads number 4 from keys_in bus and moves to state &39; code_1 &39;. . – user11551 &39;17 at 4:24. Windows users, however, must install it by themselves. Covering Transitions.
