SV--Assertions断言 SV--Assertions断⾔ SV -- Assertions 断⾔ ⽬录 1.简介 断⾔assertion被放在verilog设计中,⽅便在仿真时查看异常情况。当异常出现时,断⾔会报警。⼀般在数字电路设计中都要加⼊断⾔,断⾔占整个设计的⽐例应不少于30%。断⾔的作⽤:检查特定条件或事件序列的出现情况...

Not much to add here because a lot of it reads like asserting Storm or other players not using and sweeping with these styles is proof that they're not broken. While I do think Storm might be overblowing the dominance of Sun-Room GF for example, that kind of assertion isn'...
This is the aspect that feels like "looking to start fights" because there isn't a solid basis to respond and discuss around coming from the posts made, just antagonizing or emphasizing a problem without a solution or approach proposed. Assertion like this doesn't add to the point beyond se...

After writing this bit, the controller change is confirmed through the assertion or deassertion of the FSM_WR_CTRL_STATUS bit of the CTRL_STATUS (1Ah) register as described below: • FSM_WR_CTRL_STATUS equal to 0: all the device registers are writable from the standard interface only. ...
