Static ERC Check (static_erc)
Description
Performs various electrical rule checks and reports devices with violations.
The results are reported into a file with the extension static.xml, which can be read with a web browser.
This check is only supported by XPS and APS.

|
Digitize parameters
|
vlth
|
0.2 V
|
Voltage below vlth is considered GND. Default is 0.2V. Applicable only with gate2power, gate2ground and hotwell.
|
|
vhth
|
0.8 V
|
Voltage above vhth is considered VDD. Default is 0.8V. Applicable only with gate2power, gate2ground and hotwell.
|
|
vpth
|
-0.4 V
|
PMOS threshold voltage. This value is used to calculate the voltage drop across a PMOS channel during voltage propagation. Default is -0.4 V.
|
|
vnth
|
0.5 V
|
NMOS threshold voltage. This value is used to calculate the voltage drop across a NMOS channel during voltage propagation. Default is 0.5 V.
|
|
pwl_time
|
infinity
|
Time for pwl src to be considered as constant vsrc.
|
|
vsrcnodefile
|
[...]
|
Defines file from which node voltages are read for performing the check.
|
Filtering parameters
|
error_limit
|
10000
|
Maximum number of errors reported. Default is 10000.
|
Wildcard scoping
|
inst
|
[...]
|
Subcircuit instances to which the check is applied. Default includes all instances (inst=*).
|
|
xinst
|
[...]
|
Subcircuit instances to be excluded from the check. Default is none.
|
|
subckt
|
[...]
|
The instances of the specified subcircuit to which the check is applied. Default includes all subcircuits (subckt=*).
|
|
xsubckt
|
[...]
|
The instances of the specified subcircuits that are excluded from the check. Default is none.
|
|
depth
|
8
|
Hierarchy levels (starting from top, instance, or subcircuit scope) to be checked. Default is 8.
