set_global_assignment -name VERILOG_NON_CONSTANT_LOOP_LIMIT 300。 此时循环次数上限修改为 300,实测最大循环上限为 5000,这是很多Verilog教材中没有提到的。 方法二:当然就是换一个循环语句了,用for之类的循环不香么。 (2)for循环 格式: for(initial_assignment; condition ; step_assignment) begin … end ...

- This section details how the SystemVerilog Assertion (SVA) syntax works and how assertions can be used for design and verification. Special macro-techniques are shown to reduce assertion coding effort by up to 80%. What is an assertion? / Who should add assertions? Assertion benefits - bug...

Regions that are designed to implementconcurrent assertion checking: Preponed, Observed, and Reactive regions. Region thatshould be avoided: Inactive region. 不同region的作用 preponed event region 主要作用是并行断言在这个region中进行采样,每个time slot只执行一次(没有反馈路径能在一个slot中执行多次preponed...
