You can specify state information for individual analyses in two ways:
- You can use the
icparameter of the transient analysis to choose which previous specifications are used. You can choose from the following settings:
- You can use the
|
Parameter setting |
Action taken |
|---|---|
|
node |
The |
|
dev |
The ic parameter settings on the capacitors and inductors are used, and the ic statements are ignored. |
|
all |
Both the ic statements and the ic parameters are used. If specifications conflict, ic parameters override ic statements. |
- You can specify initial conditions and estimate solutions by creating a state file that is read by the transient analysis. For example, you can save the solution at the final point of a transient analysis and then continue the analysis in a later simulation by using the state file as the starting point for another transient analysis. You can also use state files to create automatic updates of initial conditions and nodesets.
You can instruct the simulator to write a state file from the initial point in an analysis, by using thewriteparameter. The following example writes a state file namedua741.tran.
timeDom tran stop=1u readns="ua741.tran" write="ua741.tran"
You can also instruct the AMS Designer simulator to create a state file in the transient analysis for future use.
