求助：IBIS模型转化问题

刚接触SQ仿真，遇到如下问题，请高手们不吝赐教：
1.将IBIS模型转化为dml格式后，在Signal Model Assignment界面下，赋给芯片相应的模型后，发现芯片有部分管脚使用赋给的模型，而部分管脚却使用系统黙认的模型，这是为什么?编辑模型时，提示错误如下：
model Hi3520V100_PBGA768 defines pin Y04 which doesn't exist in component SN2116_V83_FINAL U9
model Hi3520V100_PBGA768 defines pin Y03 which doesn't exist in component SN2116_V83_FINAL U9
model Hi3520V100_PBGA768 defines pin Y02 which doesn't exist in component SN2116_V83_FINAL U9
model Hi3520V100_PBGA768 defines pin Y01 which doesn't exist in component SN2116_V83_FINAL U9
model Hi3520V100_PBGA768 defines pin W04 which doesn't exist in component SN2116_V83_FINAL U9
model Hi3520V100_PBGA768 defines pin W03 which doesn't exist in component SN2116_V83_FINAL U9
model Hi3520V100_PBGA768 defines pin W02 which doesn't exist in component SN2116_V83_FINAL U9
（注 该芯片是PGA封装，且厂家提供的PIN管脚是字母加数字的）
2.提取网络时，在点击Reports查看报告和Waveforms查看波形时，弹出如下警告：
WARNINGS:
No 'V Measurement' is defined in the delay measurement fixture of model ATP8624_SP018W_PCIX. The buffer delay is assumed 0.
这是什么原因造成的?会产生什么影响?
再次谢谢大家。

是我的表达不清楚吗，怎么没人回答啊?

1.第一个是ibis定义的pin对应不上这个component的pin，谨慎怀疑是你们的component pin定义的没有“0”（譬如W01可能是W1）；
2.ATP8624_SP018W_PCIX应该是个output或者IO，ibis规范需要定义vmeas参数去计算buffer delay；如果你不需要计算时序基本可以不用理睬

  wakinoda,太谢谢你了，我按你说的做，一下子就把困扰我几天的问题解决了，你真厉害，哈！
