我用的是tsmc65nm仿真比较器失调,但是结果很奇怪,它是竖着分布的
我怀疑是我改错了lib_path/crn65gplus_2d5_lk_v1d0p1.scs文件里的代码:
代码里有两句提示:
NOTE:
// 1. To have the mismatch simulation result, the stat_mis_xxx libraries have to be included
// with an interested corner (TT/FF/SS/FS/SF) together at the same time.
// 2. Only the process variation simulation is supported in mc_xxx MOS statistical
// model library in this release version. To have the process variation result,
// the stat library is required to include with mc_xxx together at the same time.
以下是我的修改
我在section mc里,添加了两个include,引用stat和stat_mis
并在section stat_mis里面添加了Parn1的初值(这个地方我按照报错改的,但我并不知道是不是可以直接这么写)
section stat_mis
parameters parn1=0
parameters parn2=0
parameters parp1=0
parameters parp2=0
//上面四行是修改
statistics {
mismatch {
vary parn1 dist=gauss std=1/1
vary parn2 dist=gauss std=1/1
vary parp1 dist=gauss std=1/1
vary parp2 dist=gauss std=1/1
}
}
endsection stat_mis
垦请大神指教!
