What is the correct use for the SKILL command ?
sch_update = schCheckHierConfig( cfgId path libs )

This SKILL function was created in the Cadence DFII 4.4.0 release;
and it has been public, documented, and unchanged since (up to and
including the latest upcoming IC & ICOA 5.1.41 releases.

Interestingly, out of the last 700 SKILL surveys (now an integral
part of DFII for Customers owning licenses for product 900 SKILL
Development Environment) ... not one organization has indicated
their use of this function in their custom SKILL code.

Just as interestingly, only two Customers have ever asked about
this function - one request came from France and one from Germany.

From the German Customer request (which was easier for me to decipher):

"Hier eine kurze Beschreibung der Funktionen mit kleinen Beispielen:"

schCheckHierConfig
schCheckHierConfig(
h_cfgId
[ v_pathVector [g_refLibs] ]
)
=> l_errors | nil
Description
Performs a check of the hierarchy. The check starts with the top cellview
that is specified in the given hierarchy configuration. The hierarchy
traversed is defined by information in
this hierarchy configuration. Usually, the hierarchy is confined to the
library of the given cellview, but you can specify a list of reference
libraries to process if the hierarchy extends
beyond the current library.

You must have write permission to any cellview that is to be checked.
Uses the following environment settings:
checkAlways specifies whether to check every cellview regardless of
the extraction status. When nil, cellviews are checked only if they
need it.

updateConn specifies whether connectivity extraction is performed on
all schematics encountered.

runSRC specifies whether the SRC is run on all schematics
encountered.

runVIC specifies whether the VIC is run on all cellviews encountered.

checkHierSave specifies whether processed cellviews are automatically
saved. If nil, you must explicitly save and close the cellviews
processed, or any updates are
lost.

saveAction specifies what to do for those cellviews containing errors
when checkHierSave is t. Possible values are "Save", "No Save", and
"Ask Me".

The given cellview ID must be an editable schematic. If a cellview contains
any of the following property values, it is not processed:

nlAction == { ignore | stop }

schType == { border | patchCord | ripper | noSchEdit }Arguments

h_cfgId
The ID of a hierarchy configuration that specifies an expansion.

v_pathVector
The optional ID of a hierarchy configuration path vector. If not
specified, the traversal starts from the top cellview specified in
the configuration. Otherwise, the traversal
starts from the current cellview defined by this argument.

g_refLibs
A list of library names, or a string containing a list of space-
separated library names.

Value Returned

l_errors
A list of the errors encountered during the checking of the hierarchy
as defined by the given configuration object. Each element in the
list contains the cellview ID and the
number of errors encountered; no information is generated if only
warnings were encountered.

nil
No errors are found in the hierarchy.

Examples

cfgId = deGetConfigId( getCurrentWindow( ))

schSetEnv( "checkHierSave" t )

schSetEnv( "saveAction" "Save" )

errs = schCheckHierConfig( cfgId )

cfgId = deGetConfigId( getCurrentWindow( ))

path = deGetVector( getCurrentWindow( ))

errs = schCheckHierConfig( cfgId path "libA libB" )

If errors are encountered, errs is a list of cellview/number-of-errors
pairs. You can process this list as follows:

foreach( x errs

info( "%s %s %s has %d error(s).\n" car(x)~>lib~>name

car(x)~>cellName car(x)~>viewName cadr(x))

)

Likewise for the similar function:

schCheckHier

schCheckHier(
d_cvId
t_viewNames
t_refLibs
[ l_instViewListTable ]
)
=> l_errors | nil

Description

Performs a check of the hierarchy that starts at the given cellview.

The hierarchy traversed is defined by t_viewNames. Usually, the hierarchy
is confined to the library of the given cellview, but you can specify a
list of reference libraries to process
if the hierarchy extends beyond the current library. You must have write
permission to any cellview that is to be checked.

Uses the following environment settings:

checkAlways specifies whether to check every cellview regardless of
the extraction status. When nil, cellviews are checked only if they
need it.

updateConn specifies whether connectivity extraction is performed on
all schematics encountered.

runSRC specifies whether the SRC is run on all schematics
encountered.

runVIC specifies whether the VIC is run on all cellviews encountered.

checkHierSave specifies whether processed cellviews are automatically
saved. If nil, you must explicitly save and close the cellviews
processed, or any updates are
lost.

saveAction specifies what to do for those cellviews containing errors
when checkHierSave is t. Possible values are Save, No Save, and
Ask Me.

The given cellview ID must be an editable schematic. If a cellview contains
any of the following property values, it is not processed:

nlAction == { ignore | stop }

schType == { border | patchCord | ripper | noSchEdit }

Arguments

d_cvId
Cellview ID of the root schematic from which to begin the
hierarchical check.

t_viewNames
String containing the list of view names to use to control the
hierarchy traversal. Use string values in quotes.

t_refLibs
String containing the list of reference libraries to process
in addition to the library of the given cellview.
Use string values in quotes.

l_instViewListTable
Optional list specifying the instance view list table to use if
instance-based switching is required. This list contains sublists
that map a logical name to a view name list. If
an instance is encountered that has an instViewList property whose
value matches one of the logical names in the instance view
list table, the view name list associated with the logical name
is used for the hierarchical switch for that instance.

Value Returned

l_errors
A list that containing sublists of the ID of the cellview and the
number of errors encountered.

nil
No errors are found in the hierarchy.

Example

cvId = dbOpenCellViewByType( "mylib" "top" "schematic" "" 'a )

schSetEnv( "checkHierSave" t )

schSetEnv( "saveAction" "Save" )

errs = schCheckHier( cvId "schematic cmos_sch" "" )

Checks the hierarchy starting at top schematic in the library mylib where
the traversal is controlled by the given view name list. If errors are
encountered, errs is a list of
cellview, number of errors pairs. You can process this list as follows:

foreach( x errs

info( "%s %s %s has %d error(s).\n" car(x)~>lib~>name

car(x)~>cellName car(x)~>viewName cadr(x))

)

Ich hoffe, das hilft Ihnen weiter. Ueber ein kurzes Feedback wuerde ich mich
freuen.
