Exalto is a powerful post-LVS RLCk extraction software that enables IC design engineers to accurately predict electromagnetic coupling effects during the sign-off phase.
Exalto can capture unknown crosstalk among different blocks in the design hierarchy by extracting lumped-element parasitics and generating an accurate model for electrical, magnetic and substrate coupling. Exalto interfaces with most LVS tools and can complement the RC extraction tool of your choice.
With Exalto you can:
The unprecedented capacity of the Helic modeling engine at the core of Exalto enables you to analyze extremely complex layouts with ease. Complex coupling scenarios between sensitive RF circuitry with large digital busses/control signals are easily captured using the “point-and-click” interface in Exalto.
A unique netlist reduction methodology makes the output netlist extremely compact (over 90% reduction in elements and nodes compared to the native netlist) which further extends the size of the problem that can be resolved using Exalto. Traditional RC extractors with added high frequency (Lk) options run into a capacity bottleneck due to the fact that the output netlist is too large to simulate. Netlist reduction in Exalto mitigates this issue and increases its capacity by an order of magnitude.
Exalto is built with Helic’s modeling engine, the fastest electromagnetic engine in the industry. This means that the EM extraction of a 600umX400um, dense, 7 metal layer power grid takes a few minutes or the coupling model between all the spirals in a power amplifier to the key digital lines takes a few seconds.
Exalto interfaces seamlessly with 3rd party LVS tools such as Cadence PVS, Mentor Graphics Calibre LVS and Synopsys ICV. Exalto output can be automatically combined with the outputs of 3rd party LPE tools such as Cadence Quantus QRC, Mentor Graphics Calibre PEX and Synopsys StarRC. Exalto also supports “extracted views” and “extracted netlists”.
With Exalto you can generate:
