primepower 一跑就挂有何办法?
谢谢!
pp版本只有06,db是10的,但是06的版本是最新了
有其他软件可以做功耗分析吗,谢谢
......
那只能换cds的试试了。
网上找个2010的版本吧。
连基本的常识都没有。
老tool怎么支持新的语法?
我弄错了
应该是syn_vD-2010.03这个里面的Power Compiler
好像Synopsys不更新PrimePower了
具体的你问问Synopsys的技术支持 Cadence的SOC encounter中有encounter power system也可以做功耗分析
Additional Features in PrimeTime PX
Event-based dynamic power analysis using VCD or SAIF
· RTL and gate-level VCD and SAIF support
· Instantaneous and cycle-accurate peak power analysis
· Average power analysis
· State-dependent leakage power analysis
· Analysis of advanced low power design techniques: multi-voltage, coarse-grain MTCMOS
· Clock tree power estimation
· Power analysis driver GUI window
· Distributed Peak Power Analysis
· UPF support
· Supports industry-standard NLPM and CCS Power libraries
------------------------------------------------------------------------------------------
Power Compiler offers the following power analysis features:
· Performs gate-level power analysis.
· Analyzes net switching power, cell internal power, and leakage power.
· Accepts input as either user-defined switching activity, switching activity from RTL or
gate-level simulation, or a combination of both. The default is vector-free.
· Propagates switching activity during power analysis to nonannotated nets.
· Supports sequential, hierarchical, gated clock, and multiple-clock designs.
· Supports RAM and I/O modeling using a detailed state-dependent and path-dependent
power model.
· Performs power analysis in a single, integrated environment at multiple phases of the
design process.
· Reports power at any level of hierarchy to enable quick debugging.
· Reports capability to validate your testbench.
· Supports interfaces to NC-Sim, MTI, VCS-MX, Scirroco, and Verilog-XL simulators for
toggle data.
PTPX用来代替PrimePower
算是个SignOff的tool
除了Power Compiler之外,应该还有别的公司的工作做功耗分析不错吧,大家都有用过吗?
补充一下,power artist 原来叫power theather,sequence被apache收购了以后改
叫power artist.
power artist 和 spyglass还可以在RTL阶段来做power分析, PTPX不可以。
power artist 还可以在RTL时候做power debug & reduction。如果使用PACE的
technology,RTL算出的功耗和signoff的功耗的误差可以控制在20%以内。
