CIRCUIT DESIGN SUPPORT APPARATUS AND A METHOD

A circuit design support apparatus partially converts a description of a circuit model to simulate the circuit operation. A register signal replacement section replaces a register signal with a variable in a process related with the register signal of the description and inserts a declaration of the variable in the process instead of a declaration of the register signal in the description. A clock signal simplification section replaces a clock signal with a variable in a clock signal reference process of the description and unifies a clock signal update process to the clock signal reference process in the description.
