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. See more A covergroup can contain one or more coverage points. A coverage point can be an integral variable or an integral expression. Each … See more The coverage model is defined using Covergroup construct. The covergroup construct is a user-defined type. The type definition is written once, and multiple instances of that type … See more

WebJul 7, 2024 · Abstract. This chapter explores SystemVerilog functional coverage in detail. It discusses methodology components, covergroups, coverpoint, and various types of “bins” including binsof, intersect, cross, transition, wildcard, ignore_bins, illegal_bins, etc. The chapter also discusses sample/strobe methods and ways to query coverage.
