但由于条件不完整,它会推断出latch。 SystemVerilog优点九:priority,unique0和unique修饰符提供了内值的检查,能捕捉许多在使用parallel_case和full_case时可能出现的危险。 SystemVerilog优点十:priority,unique0和unique也可配合if...else决策一同使用,会提供与在case语句上使用时相同的综合优化指示,包括仿真检查,以确保...
这些结构指定用户意图,并允许模拟器正确模拟 RTL 的行为,以减少 RTL 和最终门级网表之间模拟不匹配的可能性。还有 unique 和 priority 等关键字,允许模拟匹配综合指令并确保设计正确。 考虑图 1,其中 always_comb 语句要求模拟器验证所包含的逻辑是组合的,并且应检查单独的 if 子句并将其作为并行情况实现。 module...

- New operator and enhanced loop control have been added for improved design & verification. New always_type blocks show design intent and help ensure construction of proper hardware designs. Enhancements were added to tasks and functions to increase their capabilities. Unique and priority are new ...
