What is wire load model? wht does it signify?

wire load model

In order to model the wires we use a concept called as Wireload model in Synthesis..So wireload model is something which calculates the net delay based on the fanout of a particular gate..Basically its a statistical based model which gives the prelayout estimation
Hope u got this concept
if u hv doubt still u can ask me
Bye

Re: wire load model

before P& R ,you have no idea of the real wire delay , you should have wire model!

wire load model

cell delay and net delay is used to caculate the timing of circuit , here WLM is used to caculate the net delay value, in design flow, different WLBs will be used in different stages.
