Adding Conditionality to Resilient Bundled-Data Designs

Abstract

We describe a practical method of generating production ready timing violation resilient asynchronous circuits with conditional communication from a high level hardware description language. Designs written in SystemVerilogCSP are taped out on a 3.3 million transistor chip. We present two slackless scan-enabled asynchronous controllers based on the Click template that saved an average area of 14% in our application.
