Concurrent timing optimization of latch-based digital systems

Many design techniques have been proposed to optimize the performance of a digital system implemented in a given technology. Each of these techniques can be advantageous in particular applications, and they are often applied individually to enhance performance. Previous results had shown that signi cant enhancement could be achieved when several optimizations were applied concurrently to systems with edge-triggered ip- ops. However concurrent optimization framework does not exist for systems with transparent latches. It motivates us to formulate the concurrent optimization as a mixed integer linear programming for digital systems with transparent latches. This methodology is applicable to optimize a broad range of digital systems originally designed under either single or multi-phase clocking. In addition, we present a new optimization technique - resynchronization, which allows the insertion of latches in the shortest paths and thus avoids race condition. As a result, our framework i...
