Design and design automation of rectification logic for engineering change
In a later stage of a VLSI design, it is quite often to modify a design implementation to accommodate the new specification, design errors, or to meet design constraints. In addit...

State encoding of large asynchronous controllers
A novel method to solve the state encoding problem in Signal Transition Graphs is presented. It is based on the structural theory of Petri nets and can be applied to large specifi...

A timing analysis algorithm for circuits with level-sensitive latches
For a logic design with level-sensitive latches, we need to validate timing signal paths which may flush through several latches. We developed efficient algorithms based on the mo...
