CGCap (Clock Gating Capture), is a tool for dynamic power management that implements a solution
for the automatic instantiation of clock gating circuitry in an RTL netlist.
CGCap is largely based on the PowerChecker design flow. More precisely, CGCap can only be
invoked once the PowerChecker database has been created on the design under consideration. As in the
case of PowerChecker, CGCap also requires the possibility to interface with an RTL simulator; it can
be customized to any existing simulator that supports the VCD (Value Change Dump
