Skill Exec

Execute SKILL Code on Virtuoso

Run SKILL expressions via virtuoso skill exec and parse results.

Quick reference

# Arithmetic
virtuoso skill exec "1+2" --format json

# String operations
virtuoso skill exec 'strcat("hello" " " "world")' --format json

# List all libraries
virtuoso skill exec 'foreach(mapcar lib ddGetLibList() lib~>name)' --format json

# List cells in a library
virtuoso skill exec 'let((lib) lib=ddGetObj("myLib") foreach(mapcar c lib~>cells c~>name))' --format json

# Get cell views
virtuoso skill exec 'let((cell) cell=ddGetObj("myLib" "myCell") foreach(mapcar v cell~>views v~>name))' --format json

# Current cellview info
virtuoso skill exec 'let((cv) cv=geGetEditCellView() list(cv~>libName cv~>cellName cv~>viewName))' --format json

# Instance count
virtuoso skill exec 'let((cv) cv=geGetEditCellView() length(cv~>instances))' --format json

# Net names
virtuoso skill exec 'let((cv result n) cv=geGetEditCellView() result=nil n=0 foreach(net cv~>nets when(n<20 result=cons(net~>name result) n=n+1)) result)' --format json

# Schematic read (read-only)
virtuoso skill exec 'let((cv) cv=dbOpenCellViewByType("lib" "cell" "schematic" nil "r") sprintf(nil "inst=%d nets=%d" length(cv~>instances) length(cv~>nets)))' --format json

Important notes

• Use --format json for structured output (auto in pipe mode)
• Use --timeout N for long-running operations (default 30s)
• SKILL strings use ", escape with \" inside bash single quotes
• let blocks work for local variables; Ocean functions (simulator, design, run) must be at top level
• View names may not be standard schematic — check with v~>name not v~>viewName
