Verilog code coverage analysis tool
Covered is a Verilog code coverage utility that reads in a Verilog design and a generated VCD/LXT dumpfile from that design and generates a coverage file that can be merged with other coverage files or used to create a coverage report. Covered also contains the GUI coverage report utility that reads in a coverage file to allow interactive coverage discovery. Areas of coverage measured by Covered are: line, toggle, memory, combinational logic, FSM state/state-transition and assertion coverage.
