- condition是一个逻辑表达式,表示一个条件,statement是在该条件为真时执行的操作。 -可以在一个when else语句中使用多个条件和对应的操作。 - else子句是可选的,用于指定在其他条件都不为真时执行的默认操作。 第三步:详细说明when else语句的工作流程(400-500字) -执行when else语句时,VHDL编译器会按照条件的...
In turn, when breakassertlevel is set to 1, the simulation will be stopped when an assertion with the warning severity level is encountered. Therefore, when the default value is used, the simulation continues after the error message.
process(qout) 前面一行少一个begin

I learned that the VHDL process the code in parallel unless we don't use 'process statement ' But I don't use 'process statement' in first code, but I think the first code look like being processed in sequential. The reason why I think is when i test the code in Model_sim, I ...
