TCL/script to get the Custom variables variant specific Values and transfer to a customer variable?

MZ20250602835 

Please try the script below, as it will update the custom variable value by reading from the variant.

For the purpose of this example, I've taken the first value of the variable from Variant in case of multiple variants.

proc checkFuncVar {} {

# puts "entering check mode"
set toolVar [lindex [cps::getAppVersion] 0]

set lDesigName [sch::dbGetRootDesignName]
cpb::extractFile "worklib/$lDesigName/variant/variant.dat" {variant.dat}
set filename "variant.dat"
set pattern "CV_"
set fp [open $filename r]
set functiontest {}
while {[gets $fp line] >= 0} {
if {[string match -nocase "*$pattern*" $line]} {
# puts $line
lappend functiontest $line
}
}
close $fp
return $functiontest
if {[file exists $filename ] == 1} {

file delete $filename

}

}

set data [checkFuncVar]

set lCustVar {}
set regex {\{\s*(CV_\w+)\s*=\s*'([^']+)'\s*;?\s*\}}

set valuesOnlyList {}
foreach {full _ rawValue} [regexp -all -inline $regex $data] {
set innerDict {}
foreach pair [split $rawValue |] {
lassign [split $pair =] k v
dict set innerDict $k $v
}
lappend valuesOnlyList $innerDict
}

# Example: print each values-only dict
foreach d $valuesOnlyList {
# # puts "prop : [llength $d ]"
# puts "prop : [lindex $d 0]"
set lLength [llength $d]
for {set i 0} {$i < $lLength} {incr i} {


set lPropName [lindex $d $i]
incr i
set lPropVal [lindex $d $i]
# puts $lPropName
# puts $lPropVal
if {$lPropName == "DOC_PART_PCBA"} {
lappend lCustVar $lPropVal
}

}
}

# puts $lCustVar
set lVarVal [lindex $lCustVar 0]
# puts $lVarVal

set lCustomVar [cps::setDirectiveValue CUSTOMVAR TEST_V1 $lVarVal STRING]

saveAll
cps::reopenProject

Try and let me know your feedbcak.

Dear CadAP,

i realised that the values will be updated after reopen the design.

But after reopen i get the warning because of the Pulse.

May i ask if is it possible to avoid this warning after reopen? or update the custom variables value without reopening the design?

Many thanks

Dear CadAP,

many many thanks again, i modified the script within checkFuncVar in order to get CV_VAR_X at one time so it works independent of the order of the variants.

happy Easter

Dear CadAP,

during test i have one issue, if the data content ~ and changed the row in this case i can`t get the value later for custom variable.

CV_VAR_1='DOC_COMPPLAN_DESC=test|DOC_COMPPLAN_NO=2100-1000|DOC_COMPPLAN_VER=00|~
DOC_PART_PCBA=5100-1000|DOC_PART_PCB_NUMBER=5100|DOC_PCBAPLAN_MOD_DATE=test_MOD_~
DATE|DOC_PCBAPLAN_MOD_ENG=test MOD_ENG|DOC_PCBAPLAN_PROD_DATE=test_DATE|DOC_PCBA~
PLAN_PROD_ENG=test_ENG';

Please try to remove the "~" from the list "valuesOnlyList" where we are storing the dict  key and value. 

Many thanks again,

the problem is solved.
