Spectre eXtensive Partitioning Simulator

Spectre® eXtensive Partitioning Simulator (Spectre XPS) is a newer generation transistor- level circuit simulator emphasizing high simulation performance and large simulation capacity, with a vision to fundamentally address the design and verification needs of full-chip low-power designs at advanced process nodes.

Spectre XPS incorporates a completely new circuit partitioning and multi-rate technology, and further extends the simulation performance and simulation capacity to effectively enable full-chip simulation at advanced process nodes. In particular, Spectre XPS supports a variation analysis capability to provide circuit designers practical assessment on design robustness.

The Spectre XPS simulation technology is integrated into the Spectre binary, sharing the same product infrastructure with Spectre and Spectre APS. The Spectre XPS use model is identical to that of Spectre and Spectre APS, with the netlist syntax, device models, analysis setups, and output formats being fully compatible. It provides transient simulation capability for SRAM timing and power analysis, EM/IR analyses with an advanced power network solver, advanced parasitic reduction for faster post-layout simulation, and a set of circuit-checking features.

Benefits of Spectre XPS

Spectre XPS provides the following benefits:

• Provides high performance and capacity pre-and post-layout simulation for design and IP characterization at the block and chip level.
• Provides a comprehensive set of transistor-level electrical rule checks.
• Delivers advanced EM and IR drop analysis for optimal throughput.
• Supports large and complex post-layout designs delivering a significant reduction in simulation runtime compared to the traditional FastSPICE simulator.
• Uses proven Spectre use-model for simplified setting up and post processing of results.
• Fully integrated into the Virtuoso Analog Design Environment (ADE).
