板上的大大們好:小弟最近run IBIS時有碰到一些問題,錯誤的訊息是
3 o+ K6 L- z8 _9 x; _ DERROR - Model [Name]: The [Falling Waveform] " o" z1 P1 W& B8 O& o: I
with [R_fixture]=60 Ohms and [V_fixture_min]=3V
9 o4 S- `% E* ?7 M5 [ has MIN column DC endpoints of 2.23V and 3.00v, but, Z, L; z! m6 |; j* x
an equivalent load applied to the model's I-V tables yields
2 H5 ?+ S; Z$ p- j+ v different voltages ( 2.10V and 3.00V),
* m" K% X* j- [/ S a difference of 6.44% and 0.00%, respectively) W$ h% L/ H) T2 e2 w- Q
在run ddr的時候出現mismatch的情形,只知道說好像是V-T轉I-V時的電壓不同,看不懂這個問題要如何解決,請版上的大大們幫我解答一下,謝謝! |
