陈版主，各位大侠：帮一下忙啊：下面的sdc文件写的对不对啊？

rfid_sh

第一次学习用soc encounter做P&R时，生成的SDF文件在后仿出现errors
步骤：


按照上面的步骤的说法，执行了（1）（2）（3）（4）步，
第（1）步是


第（2）步见上面的流程图

第（3）步是


第（4）步见上面的流程图

后仿出现的errors：
# ** Error: (vsim-SDF-3262) D:/test_for_ph/HJ2SY_14A_TOP_20110721_pm.sdf(5893): Failed to find matching specify timing constraint.
# ** Error: (vsim-SDF-3262) D:/test_for_ph/HJ2SY_14A_TOP_20110721_pm.sdf(5919): Failed to find matching specify timing constraint.
# ** Error: (vsim-SDF-3262) D:/test_for_ph/HJ2SY_14A_TOP_20110721_pm.sdf(5961): Failed to find matching specify timing constraint.
# ** Error: (vsim-SDF-3262) D:/test_for_ph/HJ2SY_14A_TOP_20110721_pm.sdf(5981): Failed to find matching specify timing constraint.
# ** Error: (vsim-SDF-3262) D:/test_for_ph/HJ2SY_14A_TOP_20110721_pm.sdf(5999): Failed to find matching specify timing constraint.

基本上是相同的errors
是不是第（1）（3）步都是默认设置，所以出错了啊？
还是需要在上面四步中设置一下选项啊？
或者是其他步骤的操作不对，引起了这一步骤生成的.sdf文件不对啊？

附上sdc文件，是不是要注销很多语句行啊？

我的也出问题了,反标出现问题,类似下面的错误
SDFA Error: Could not find path C to Y in instance tst_dsm.dsm_pr_ins.U6
还不知道怎么改.
你用的是哪个版本.
我的是encounter 9.1
和搜到的教程都不太一样.

我的encounter很老，好像是6.1的

你有教材？可以分享一下吗？

我的资料是在eetop上下载的

回复 3# rfid_sh


    跟你贴的图差不多,我在网上看到的.
基于hejian18工艺的SOC Ecounter数字版图设计流程
http://www.docin.com/p-158910271.html
它这个版本和我的也不一样.
弄的我现在都不知道得到的版图对不对.
我听说有的只输出spef做STA，然后导出sdf文件做后防
反正乱乱的,
跟你一起学习吧.

damonzhao

encounter出def
starRC读入，出SPEF
PT读入，出SDF，供后仿

dongkai1003

那个error不是说sdc没找到吗！

回复 5# damonzhao


    为什么不能用encounter直接输出的sdf文件后仿呢?
有什么说法吗?

damonzhao

回复 7# yuluw2004


    如果想signoff的话，你就得用标准流程，不然不准

yuluw2004

回复 8# damonzhao


    帮写个标准流程吧,以及每步用的谁家的工具.
我大概说说我的情况

1.verilog 代码;产生*.v给DC;
2. DC 综合,生成*_syn.v 和*.sdc给encounter
3.encounter布局布线,生成*_pr.v,*.gds2,
4.formility, primitime, verilog simu.
具体说说encounter和它之后的每一步吧.
    我现在可以做formility,
    verilog simu. 反标文件有问题
    primtime还没用过,准备去学了.

我觉得是我的.sdc文件不对啊。
有没有哪个大侠有关于写.sdc文件的资料啊？
非常感谢！

另外，第三步是不是没选FE-DC 或者是 SignalStorm啊？
