WebSep 12, 2024 · Cross Module Reference abbreviated as XMR is a very useful concept in Verilog HDL (as well as system Verilog). However it seems to be less known among many users of Verilog. XMR is a mechanism built into Verilog to globally reference (i.e., across the modules) to any nets, tasks, functions etc. WebOct 8, 2024 · The cross a1b1 from covergroup ab1 is used in the different covergroup ab1c1. The cross a1b1 is used in creating cross a1b1c1 in the covergroup ab1c1. Referencing is done in object oriented way ab1.a1b1. Please note the SystemVerilog covergroups are not object oriented.

WebTons of typos in your example. I think the following is what you want. Remember that with a cross, the only things you can do with bins is ignore or combine sets of bins tuples. covergroup cg; cp_A : coverpoint a { bins eq0 = {1'b0}; bins eq1_31 [] = {[1:31]}; } cp_B : coverpoint b { bins eq0 = {1'b0}; bins eq1_31 [] = {[1:31]}; } cp_C ... WebSep 30, 2014 · In general, a conventional two flip-flop synchronizer is used for synchronizing a single bit level signal. 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. fuji discovery 3000
