仿真错误提示:
Error found by spectre during DC analysis `dcOp'.
Matrix is singular (detected at `out' and `g').
No DC solution found (no convergence).
The values for those nodes that did not converge on the last Newton iteration
are given below. Also given is the manner in which the convergence
criteria were not satisfied in the following form:
Failed test: | Value | > RelTol*Ref + AbsTol
I(I9:vout_flow) = 0 A
residue too large: | 1.2 V | > 6 mV + 1 uV
V(net034) = 0 V
residue too large: | -314 uA | > 1.57 uA + 1 pA
V(out) = 0 V
residue too large: | 314 uA | > 1.57 uA + 1 pA
顺便说一下,EE240 2006 为一美国口音老外讲授,比bosor容易听懂,但好像没他详细 |
