Hardware for Best Simulation Performance?

SteveMarshall
SteveMarshall over 15 years ago

 We are upgrading our workstations and are wondering if Cadence software will gain a performance advantage if processors with Hyperthreading are used. We have to choose between the i7 and i5 processors. Most work done in the lab is corners and monte-carlo analysis of analog circuits, in the Analog Design Environment. The simulator is spectre.

 I am not too hopeful that hyperthreading will give a performance benefit, even to highly parallelized tasks such as Corners analysis, but if it does it would be a huge benefit. If the simulation engine can take advantage of hyperthreading, please let me know.

 

Thanks!

    Don't use core and it's hyperthread for the same simulation task. It will slow down your simulation time (but CPU usage will show higher percentage). But if you will run two simulation job at the same time you can assign one job to different processors core and another simulation job to their hyperthreads. In this case you will get the best performance.
