Dynamic Rise Fall Edge Check (dyn_risefall)
Description
The dynamic edge check detects the nodes whose voltages do not cross the user-defined thresholds VH and VL.
The results are written to the dynamic.xml file, which can be viewed in a Web browser.

Parameters
Design check parameters
|
node
|
[...]
|
Nodes to which the check is applied. Default is none.
|
|
vrefp
|
[...]
|
Power reference node to support multiple power domain.
|
|
vrefn
|
[...]
|
Ground reference node to support multiple power domain.
|
|
vhr
|
0 V
|
Relative high voltage ratio for rise/fall edge measurements.
|
|
vlr
|
0 V
|
Relative low voltage ratio for rise/fall edge measurements.
|
|
type
|
|
Check rise or fall edge.Possible values are rise and fall.
|
|
vh
|
0 V
|
High voltage threshold for rise/fall edge measurements.
|
|
vl
|
0 V
|
Low voltage threshold for rise/fall edge measurements.
|
Filtering parameters
|
time_window
|
[tstart, tstop] sec
|
Time window to which the circuit check is applied. Multiple non-overlapping time windows are supported. Default time window is 0 to tend.
|
|
error_limit
|
10000
|
Maximum number of errors reported. Default is 10000.
|
|
fanout
|
all
|
Fanout setting to filter node with specified connection..Possible values are all, gate and bulk.
|
|
filter
|
optimized
|
Filter setting to report all nodes or fewer nodes of interest.Possible values are rc, optimized and none.
|
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.
|
|
monotonic
|
1
|
Flag to indicate that monotonic transitions are expected. Non-monotonic edge is reported violation. Set 0 to skip non-monotonic violations..
|
|
dvmin
|
0.01 V
|
Voltage resolution to control the sensitivity of non-monotonic checks..
|
|
duration
|
0 Sec
|
Delta voltage duration of non-monotonic checks..
