For simulating very large circuits consisting of multi-million elements, multi-threaded circuit simulation software is required. Multi-threaded SmartSpice has been in commercial use for many years, and all SPICE models, including BSIM3 and BSIM4, are multi-threaded. After extensive research and development, Simucad has completed the multi-threaded HiSIM model and released it for commercial applications.
Extensive testing has shown that the multi-threaded version of HiSIM is consistently faster than BSIM4, and often faster than BSIM3. The speed advantage is especially pronounced in very large circuits with many back-annotated parasitic R and C elements. As deep submicron circuits designed in 90nm and below technologies require back-annotation of R and C parasitics, the multi-threaded HiSIM becomes the model of choice.
“Simucad has been concentrating on the development of multi-threaded technologies for many years, and this expertise has now been applied to HiSIM. This will make HiSIM the leading model of choice for simulating technologies below 90nm,” said Dr. Ivan Pesic, President and CEO of Simucad. “The performance of this model has surprised even us.”
For easy adoption of the HiSIM model, Simucad offers a full solution consisting of 32-bit and 64-bit multi-threaded SmartSpice for analog and mixed-signal circuit simulation, UTMOST IV for automated SPICE model parameter extraction, and SPICE model parameter extraction service. SmartSpice and UTMOST IV are available for download from Simucad’s website.
