Hi All ,
I was trying to run the PLL simulations in Cadence and i get the follwoing error message .
I will appreciate for your responses
Analysis `timeSweep' terminated prematurely due to error.
finalTimeOP: writing operating point information to rawfile.
Error found by spectre during DC analysis, during info `finalTimeOP'.
Analysis skipped due to inability to compute operating point.
Analysis `finalTimeOP' terminated prematurely due to error.
modelParameter: writing model parameter values to rawfile.
element: writing instance parameter values to rawfile.
outputParameter: writing output parameter values to rawfile.
Aggregate audit (10:42:38 AM, Tue Apr 7, 2009):
Time used: CPU = 43.5 s, elapsed = 44 s, util. = 98.9%.
Virtual memory used = 1.99 Mbytes.
spectre completes with 3 errors, 4 warnings, and 0 notices
Added after 3 minutes:
Error
Error found by spectre during IC analysis, during transient analysis
`timeSweep'.
There were 7 attempts to find the DC solution. In 1 of those attempts, a
signal exceeded the blowup limit of it's quantity. The last signal that
failed is V(xi0.xi36.net183) = -1.00507 GV, for which the quantity is
`V' and the blowup limit is (1 GV). It is possible that the circuit has
no DC solution. If you really want signals this large, set the `blowup'
parameter of this quantity to a larger value.
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
Added after 25 minutes:
No worries
solved the problem
had to initialize cap tp 0 V
