PrimeTime
Signoff users generally have four key solution requirements in order to meet their design requirement needs: continuous improvement to runtime and capacity to address increasing chip size requirements, efficient multi-scenario analysis to verify timing across all corners and modes, margin control to reduce over-design and maximize chip performance, and accuracy to insure correlation to silicon. The Synopsys PrimeTime® Suite addresses these requirements by delivering fast, memory-efficient scalar and multicore computing, distributed multi-scenario analysis and ECO fixing, using advanced constraint analysis, and variation-aware Composite Current Source (CCS) modeling that extends static timing analysis to include Crosstalk Timing, Noise, Power and statistical STA.
The Synopsys PrimeTime suite, including PrimeTime, PrimeTime SI, PrimeTime PX and PrimeTime VX, provides a single, golden, trusted signoff solution for timing, signal integrity, power and variation-aware analysis. It delivers HSPICE® accurate signoff analysis that helps pinpoint problems prior to tapeout thereby reducing risk, ensuring design integrity, and lowering the cost of design. This industry gold-standard improves your team’s productivity by delivering fast turnaround to shave precious time from development schedules for large and small designs while ensuring first-pass silicon success through greater predictability and the highest accuracy.
Key benefits:
- Supports Liberty Composite Current Source (CCS) libraries providing SPICE accurate consistent analysis results.
- PrimeTime Suite includes static timing analysis tool (PrimeTime), crosstalk, noise and voltage drop calculation tool (PrimeTime SI), power consumption analysis tool (PrimeTime PX) and variation-aware analysis solution (PrimeTime VX). All these parts create a single environment which improves designer productivity, reduces set-up steps, as well as minimizes the number of interface files created and used
- PrimeTime provides golden delay calculation and widely used as a main factory sign-off tool among all market players.
- Familiar GUI and Console command interface similar to all Galaxy platform tools (such as Design Compiler, IC Compiler) which makes mastering and everyday use easer.
- Advanced multicore support allows easy server farms configuring and use whereas multithreading makes possible to utilize all the facilities that multiprocessor servers provide without extra license needed.
- Distributed Multi-Scenario Analysis enables multiple scenarios to be run concurrently which reduces wall clock time and produces a single comprehensive timing report. Coupled with features such as automated hold-fixing that reduce ECO time from days to minutes, this capability reduces timing closure turnaround time and improves engineering productivity.
- PrimeTime’s advanced on-chip variation (Advanced OCV) modeling capability extends OCV analysis to deliver an improved method of adding margin in a design. Advanced OCV uses context-specific derate factors that consider location and logic depth of each path being analyzed
- PrimeTime is a part of Synopsys Low Power Eclipse platform that allows configuring power subsystem with UPF specification and perform all types of analysis taking into account the power domain structure, power domain supply voltages etc
- Cycle accurate power analysis with VCD activity information
- Variation aware timing, power and signal integrity analysis for reducing variation pessimism and refusing of global derate factors
