(3采样值不变,则$stable返回true,否则返回false。 posege返回一个事件(event),而$rose返回一个布尔值,因此它们是不可互换的。 48、什么是覆盖率驱动的验证(coverage driven verification) 覆盖率驱动验证是一种以结果为导向(resultoriented approach)的功能验证方法。 根据测试的反馈来开发随机测试激励。初始测试可以...

The profiler helps to figure out the components or the code streams that take the maximum time or memory during simulation. Over the years, profiling was more inclined toward RTL and GLS than verification. Today, with the increase in number of performance bottlenecks found in Syste...
IEC/IEEE Behavioural Languages - Part 4: Verilog Hardware Description Language (Adoption of IEEE Std 1364-2001) The Verilog Hardware Description Language (HDL) is defined in this standard. Verilog HDL is a formal notation intended for use in all phases of the creation of electronic systems. ...
