September 2010Anasim Confidential3 Speed independent of devices Simulation time is determined only by chip area and spatial accuracy desired. Number of wires, circuit blocks, capacitances, etc. do not affect simulation speed. Simulation time is determined only by chip area and spatial accuracy desired.

September 2010Anasim Confidential5 Constraint relaxation pre-synth. Front-end analysis and optimization capability permits relaxation of routing constraints prior to place & route, speeding timing and physical design convergence. Front-end analysis and optimization capability permits relaxation of routing constraints prior to place & route, speeding timing and physical design convergence. Q: What are some of the methodology issues that limit IC layout productivity? A: Having teams with separate front-end and back-end people. You need an automated way to pass constraints for the circuit designer on the front-end to the layout designer on the back-end. Even floorplanning constraints can be set by the circuit designer.
