最近做一个assertion,要求在信号rd为高时,判断信号addr保持时间是否达到最小保持时间我写了一个assertion但是语法总是不过,求教一下这么写到底哪有问题:
property aaa;
(rd == 1) throughout( @(posedge clk) addr_dly != addr |-> ##[350] addr_dly != addr);
endproperty
assert property(aaa);
property aaa;
(rd == 1) throughout( @(posedge clk) addr_dly != addr |-> ##[350] addr_dly != addr);
endproperty
assert property(aaa);
怎么出来了个表情。 表情那个地方是 : $
