Dynamic Node Capacitance Check (dyn_nodecap)
Description
Reports the node capacitance at specified times (time) of a transient simulation. Device capacitances, grounded capacitances, and coupling capacitances are combined into one value.
The results are written to the dynamic.xml file, which can be viewed in a Web browser.
Syntax
Name dyn_nodecap parameter=value ...
Parameters
Design check parameters
|
node
|
[...]
|
Nodes for which the capacitance needs to be checked, vsrc nodes are skipped.
|
Filtering parameters
|
time
|
[...] sec
|
time point(s) at which the dynamic nodecap check is performed.
|
|
error_limit
|
10000
|
Maximum number of errors reported. Default is 10000.
|
|
fanout
|
all
|
Fanout setting to filter node with specified connection. This option is supported only in XPS.Possible values are all, gate and bulk.
|
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.
|
|
intrinsic_cap_merge
|
no
|
Merge the internal captab node to external node. Default is no. This option is supported only in Spectre and APS.Possible values are no and yes.
