What is the XA Option?
The XA Option is Synopsys’s Next-Generation patent-pending transistor level simulation technology available as an option to NanoSim and HSIM in the form of a standalone simulation engine (executable). Currently the XA Technology is targeted at SPICE acceleration applications.
- What are the benefits of the XA Option?
The XA Technology is a revolutionary simulation technology that provides customers with:
- Superior Accuracy, XA includes a full SPICE engine for it’s most accurate settings
- Superior Time to Results, XA does not require any tuning to achieve the desired performance at prescribed accuracy
- Superior Quality of Results, XA will consistently produce the same performance for prescribed accuracy regardless of changes in circuit topology or technology
I am a NanoSim / HSIM user, when should I use the XA Option?
Although sold as an option to NanoSim & HSIM the XA Option is in fact a standalone simulation engine (executable). The XA technology cannot be restricted to a particular circuit type or class of circuits. In general users turn to the XA technology when SPICE starts to run out of steam on designs where SPICE accuracy is critical. Circuits or technologies that require numerous tuning options and tuning iterations can be simulated by the XA technology with minimal tuning. Typical circuits used with XA are PLL’s, switching regulators and circuits using internally derived power supplies.
Who has used the XA Option?
Our Beta Development partners have helped us to validate this new technology (See Press Release) In addition to extensive customer testing and validation the regression suites for HSIM, NanoSim & StarSim-XT have been used to qualify the XA technology. The XA regression suite includes some of the most challenging circuits for the existing FastSPICE simulators.
What level of accuracy can I expect from the XA option?
The XA technology has been designed to deliver SPICE-like accuracy (within 1%) while providing higher performance than SPICE
What does "No Tuning" really mean?
The XA simulation technology requires the user to set the desired simulation accuracy globally or locally (from levels 1 (Low accuracy) to 7 (SPICE accuracy)) and then run the simulation. No additional tuning steps are required.
What Models does XA Support?
As with NanoSim & HSIM, the XA Option is built on top of the common HSPICE model library and therefore supports all HSPICE models. In addition to supporting HSPICE models XA supports selected Eldo models.
What Netlist Formats does XA Support?
The XA Option supports HSPICE and Eldo Netlist Format.
How much does the XA option cost?
