WebIt creates a noisy signal with a power of power and a flat frequency distribution. name may be used to combine noise sources in the output report and vectors for small-signal noise analysis. name is ignored with real-time noise analysis. Noise sources with the same name in the same instance will be combined together. WebYes, you have two ways to conditionally enable coverage.

As shown in Figure 1 and Figure 2 , flip flop A and B1 are operating in asynchronous clock domain. There is probability that while sampling the input B1-d by flip flop B1 in CLK_B clock domain, output B1-q may go into metastable state.

WebMar 5, 2024 · If you want a separate bin for each value of a coverpoint, you need to write coverpoint a { bins a_bin [256] = { [0:$]}; } Now a simple cross of a,b,c,d would create 256*256*257*256 = 2 32 cross bins. Bins of a cross are automatically generated and you only specify bins if you want them merged or ignored.
