Timing Synthesis using Timers

1 Introduction Most controllers designed today contain one or more timers which are used for accurate timing control of events on the controllers ' output signals. General purpose microcontrollers usually contain several timers which are programmed for specific applications[1, 2]. When an application specific controller is designed, however, timers must be designed anew or existing design must be picked up from a library and manually inserted into the target controller. Since this process is not supported by currently available synthesis systems, controller design cannot be fully automated. This problem can be solved by augmenting the current synthesis systems with the capability of automatically designing timers
