Typical Scenarios When Optimizing Designs

You have a design written in HDL. You have a very limited idea of the timing requirements. You simply wish to attain the fastest possible design. 

You have written your source code, you know the detailed timing requirements, from characterize or otherwise. You wish to meet these timing requirements. 

Execute the following steps in DC using the appropriate commands  

Analyze results using report constraints -alLvioiators -verbose 

Identify any multi-cycle paths and false paths that might exist in the design Create path groups using group path command.

Metamodels have been widely used in many fields of engineering, to replace rigorous mathematical models when they become too time-consuming or prone to numerical problems. One of the most typical uses of metamodels has been in optimal design where many design scenarios can be easily analysed by optimisation techniques.
