Astro-rail做功耗分析遇到问题,跪求高人解答

时间:10-02 整理:3721RD 点击:



问题一:

我在用astro按上图所示导入vcd文件时,报了如下错误:
Astro> poLoadNetSwitchingInfo
Astro>
Purging power info ...
Purging PWR view of cell encoder_routing
Successfully purged all power info
Checking logical P/G nets among soft macros ...
======================= Power Supply Info ===========================

======================= Ground Supply Info ==========================

Set user-defined hierarchical delimiter to /
File list = /home1/ic2/DAC_1402/zp/place_route/frontend/encoder.vcd, number of VCD files = 1
Parsing vcd file /home1/ic2/DAC_1402/zp/place_route/frontend/encoder.vcd, please wait ......
Create cell encoder_routing.PWR
VCD parsing time unit :1.000000e-12 sec
Variable definitions end at line #235
Error: unexpected end of VCD file near $dumpvars
Error: fail to parse VCD file /home1/ic2/DAC_1402/zp/place_route/frontend/encoder.vcd
Parsing VCD file /home1/ic2/DAC_1402/zp/place_route/frontend/encoder.vcd failed
Fail to execute command
VCD文件(在附件中)我是用modelsim按如下方法导出的:
vsim>vcd file encoder.vcd
vsim>vcd add /encoder_sim/*
vsim>run
搞不清楚是哪儿出错了,求助!

问题二:
导入VDD网络的电压值:
Astro-Rail工具用VDD的电压值来计算芯片的功耗,默认值为0V。指定VDD网络电压值的命令为:
tdfSetPowerSupply “VDD”1.62 1.8 1.98
将该命令保存在Powersupply.tdf文件,然后执行poLoadPowerSupply命令,弹出对话框输入该文件进行导入。
我按如上方法导入VDD电压值后,astro里报出结果如下:
Astro> Summary of loading power supply
Power netsminVoltage(V)nomVoltage(V)maxVoltage(V)
VDDunspecifiedunspecifiedunspecified
没搞懂是怎么回事,求助!

附:

VCD文件里的内容如下:
