karandeep963 Posted March 13, 2014 Report Share Posted March 13, 2014 I think its a fictitious thought, as who used what like it more comfortable !!! Indeed Standard Reg Model is more comfortable as to RGM thanks to Mentor's CookBook !! Quote Link to comment Share on other sites More sharing options...
abhingp01 Posted April 16, 2014 Author Report Share Posted April 16, 2014 Hi, We did simple comparison in our TB. We did following number of writes-Read on a single design register with both UVM_REG and RGM individually. (Env stays same) (We could reproduce same result on two separate simulators) 100 loops 1000 loops 10000 loops Results was the delta between uvm_reg and rgm actual simulation time was increasing. UVM_REG was much faster compared to RGM for 10,000 loops And hence we were trying to analyse why we see such a difference. (Data structure ... etc) Any further information would be helpful.

uwes Posted April 29, 2014 Report Share Posted April 29, 2014 hi, there are numerous factors affecting performance here. having looked deeply into both models i doubt that in an apple-to-apple comparison there are major differences for this use model. please provide version info and/or a testcase to check this. /uwe Quote Link to comment Share on other sites More sharing options...
