CommencezIsolate Crosstalk Root Cause, Including Electrical, Magnetic and Substrate Coupling
With Exalto, users can:
- Analyze crosstalk with high complexity nets and blocks belonging to alternate design hierarchy levels
- Combine fully coupled EM models for critical nets/passive devices with RC extracted netlists for the remainder of the circuit into a single extracted look or netlist
- Extract lumped-element parasitics and generate accurate models for large complex silicon circuits
- Compute multiple “what-if” scenarios with altering sets of critical nets without ever modifying your test bench schematic
- Automatic back-logging of the Exalto extracted model to the beginning schematic or LPE-extracted netlist, even if you extract part of the layout or the entire layout
Electrothermal Design of Power Converters for Electric Propulsion
Fastest RLCK Extraction Engine in the Semiconductor Software Industry
✔ Exalto is built with ANSYS’ latest modeling engine, the fastest electromagnetic engine in the industry.
✔ This means that the EM extraction of a 600 um X 400 um, dense, 7-metal-layer power grid takes just a few minutes.
✔ To boot, the coupling model between all the spirals in a power amplifier to the key digital lines takes a few seconds.
The Gold Standard of Post-LVS RLCK Extraction Software
- The unmatched capacity of the ANSYS modeling engine at the center of Exalto empowers engineers to analyze particularly complex layouts with ease. Complex coupling scenarios between sensitive RF circuitry with substantial digital busses/control signals are effortlessly captured using the “point-and-click” interface.
- A distinctive netlist reduction method makes the output netlist exceptionally compact, equating to a 90% reduction in elements and nodes compared to the native netlist, which further expands the size threshold that can be fixed using Exalto.
- Conventional RC extractors with additional high frequency (Lk) options run into a capacity bottleneck as the output netlist is too large to simulate. Netlist reduction in Exalto alleviates this issue and increases its capacity and processing capabilities by an order of magnitude.
- Exalto interfaces effortlessly integrate with third-party LVS tools such as Cadence PVS, Mentor Graphics Calibre LVS as well as Synopsys ICV.
- In addition, Exalto output can be automatically linked with the outputs of third-party LPE tools such as Cadence Quantus QRC, Mentor Graphics Calibre PEX and Synopsys StarRC. Exalto also supports “extracted views” as well as “extracted netlists.”
With Ansys Exalto, users you can produce:
- Passive, causal DC accurate S-parameter models appropriate for AC, harmonic balance and SP analyses.
- Passive, causal and highly compact RLCk netlist models appropriate for transient, shooting, as well as noise analyses
- SPICE/SPECTRE setup and formatting RLCk netlists that can always be simulated.
- Ansys Exalto can extract full analytical capacitive coupling between overlaying inductors with underlying devices.
- It leverages existing foundry-characterized intra-device models for capacitors and transistors and then lumps total coupling capacitance to device terminals only.
- Exalto has the capacity and speed to extract full capacitive coupling even for thousands of devices.
- Run multiple “what-if” scenarios with different sets of critical nets, without ever touching your test bench schematic.
