也可以使用+sdfverboseruntime option来打印所有反标消息 "mtm_spec":指定延迟类型"MINIMUM(min)", "TYPICAL(typ)"或者"MAXIMUM(max)"。 "scale_factors":分别指定min:typ:max的缩放因子,默认是"1.0:1.0:1.0" "scale_type":指定缩放之前延迟值得来源,"FROM_TYPICAL","FROM_MIMINUM", "FROM_MAXIMUM"和"FROM_...

For example, to specify only the SDF file and the instance it applies to: $sdf_annotate("myasic.sdf", testbench.u1); To also specify maximum delay values: $sdf_annotate("myasic.sdf", testbench.u1, , , "maximum"); Model Technology Incorporated Voice: (503) 641-1340 Fax: (503...
"scale_type":指定缩放之前延迟值得来源,"FROM_TYPICAL","FROM_MIMINUM", "FROM_MAXIMUM"和"FROM_MTM" (default). 下面通过一个振荡环(ring_oscillator)示例sdf文件和$sdf_annotate的用法。 ring_oscillator.v 代码语言:javascript 复制 `timescale 1ns/1ps ...
