This appendix describes the environment variables you can use for Spectre Interactive Environment:
- $SIE_RUN_VIRTUOSO
- $SIE_EDITOR <command>
- $SIE_SPECTRE_TIMEOUT <num>
- $SIE_GET_INSTS_TIMEOUT <num>
- $SIE_RES_VALUE_DIGITS <num>
- $SIE_RES_TIME_DIGITS <num>
- $SIE_INST_LIMIT <num>
$SIE_RUN_VIRTUOSO
When set, runs Virtuoso to plot graphs in ViVA XL. Otherwise, ViVA XL is opened in standalone mode.
Default value: By default, this variable is not set.
$SIE_EDITOR <command>
Specifies the editor to be used to open the files for viewing or editing. The command contains the name of the exe for the text editor to be opened. This variable is used when viewing the input files by using the View – View Inputs Files command.
Default value: By default, this variable is not set. This means, the input files are opened in the default dialog as view-only. You cannot edit the files in the default dialog.
Example: setenv SIE_EDITOR 'nedit'
$SIE_SPECTRE_TIMEOUT <num>
The maximum time (in seconds) for which Spectre Interactive Environment waits for Spectre to start.
$SIE_GET_INSTS_TIMEOUT <num>
The maximum time (in seconds) for which Spectre Interactive Environment waits to get the instance information from the Spectre netlist file.
$SIE_RES_VALUE_DIGITS <num>
Sets the number of digits up to which the numeric values in the simulation results are displayed.
$SIE_RES_TIME_DIGITS <num>
Sets the number of digits to be used to display the time values in simulation results.
$SIE_INST_LIMIT <num>
Sets the maximum number of instances to be returned by Spectre from the netlist file. If the number of instances in the netlist is more than the limit set by this variable, an appropriate warning message is displayed.
