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. WebApr 22, 2010 · Explicit can mean many different things. It probably refers to the way the pin connections are defined in the actual instantiation, all sub-module pins are named, as opposed to an instantiation that uses pin order to connect to the sub module pins.

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 ... “bins” keyword is used to declare the bins explicitly to a variable.
