Abstract
To meet the demand for higher performance, today´s logic simulators are supporting 2 state simulation. Within Chronologic Simulation´s VCS simulation system, we have implemented an elaborate infrastructure to support mixed 2-4 state simulation in Verilog. The paper presents our approach to allow mixed 2-4 state simulation while retaining compliance to Verilog HDL language and its simulation semantics. The key issues that need consideration for mixed 2-4 state simulation are discussed in detail. The results obtained by running VCS regression test suite and OVI regression test suite are summarized
