If in ASIC synthesis domain: De$ign Compiler ---> Phy$ical Compiler,fbiair said:what is different Amplify with Synplify ?
One of my co-worker tested FPGA compilerII and synplicity. (Amplify I think is the physical optimization, it is still synplicity sythesis system.) FPGA compiler II compiles the code much faster than synplicity but the resulting FPGA runs a LOT slower and bigger. I also tried Xilinx XST. The compile time is a LOT slower than synplicity. So FPGA compiler II is the fastest compiler I ever tested and also the worst result (much worst, not even 50% of what synplicity gives in clock speed.) XST and synplicity were very close. In fact, if I remember correctly, XST results slightly high clock speed than synplicity but takes a little more gates. Also, XST has certain restriction on how I/O cell instantiate within hiarc level.fbiair said:Hi friends,
Who can tell me ?
Compare FPGA CompilerII 3.7 with Synplicity Amplify 3.1 , and you think
which better ?
Thanks for your idea !
