Explicit bins in system verilog

WebCAUSE: In a module declaration at the specified location in a Verilog Design File , you attempted to create an explicit (named) port using the specified port identifier. However, you have already used the specified port identifier to declare another explicit port in the module's list of ports. All explicit port identifiers must be unique. “bins” keyword is used to declare the bins explicitly to a variable. A separate bin is created for each value in the given range of variable or a single/multiple bins for the rage of values. Bins are explicitly declared within curly braces { } along with the bins keyword followed by bin name and variable value/range, … See more Functional coverage is a user-defined metric that measures how much of the design specification has been exercised in verification.

http://testbench.in/CO_11_IGNORE_BINS.html WebJun 3, 2024 · 1 Answer. Yes. The option auto_bin_max sets the maximum number of bins that will be created automatically. So, with an 8-bit variable a (as you have here), instead of creating 256 bins (one bin per value), you get auto_bin_max bins. When auto_bin_max is set to 64 for covergroup instance gv1 (which is actually its default value anyway), so you ...
