Legendís MSIM supports BSIM4.3.0 model for nanometer designs
SANTA CLARA, Calif., -- February 12,
2004 - Legend Design Technology, Inc. today announced the
MSIM circuit simulator provides full modeling support of BSIM4.3.0
for nanometer process technology. MSIM is a high-accuracy circuit
simulator with post-layout RC reduction capability.
MSIM with new BSIM4.3.0 model has been successfully used for
simulating state-of-the-art 90 nm CMOS memory designs by major
foundry customers. It has been observed that the MSIM simulation
results show there is approximately a 3 % difference when
considering stress effects (SA, SB) while measuring rise and fall
For BSIM4.3.0 support, MSIM has been built to handle
the additional electrical mechanisms, model parameters and equations
associated with the new model. This includes:
"Device modeling in circuit simulators
is essential for silicon success of deep-submicron and nanometer SOC
designs. Based upon our clientsí needs, Legend has successfully
implemented the BSIM4.3.0 model in MSIM to offer an accurate and
reliable simulation solution." said Dr. You-Pang Wei, president and
chief executive officer of Legend Design Technology. "We are fully
committed to provide robust circuit simulators that support the
sophisticated and updated models associated with nanometer SOC
- A new scalable stress effect model for process induced stress
- where device performance becomes a function of the active area
geometry and the location of the device in the active area.
- A unified current-saturation model that includes all
mechanisms of current saturation, velocity saturation, velocity
overshoot and source end velocity limit.
- A new temperature model format that allows convenient
prediction of temperature effects on saturation velocity,
mobility, and S/D resistances.
- Enhanced accuracy and flexibility of holistic thermal noise
- Improved accuracy of forward body bias model, and
- Extension of gate direct tunneling model to multiple-layer
