5.33.9 Handling exceptions (Tcl scripting)

To control the flow of the Designer software based on certain conditions (for example, success or failure of certain commands), you can use the Tcl built-in catch command as follows:

if { [ catch {open_design $des_name.adb} ] } { puts "Cannot open $des_name.adb"

export -format "log" -diagnostic $des_name.log" exit 1

} else {

puts "Design $des_name.adb Successfully Opened"

}

## set layout mode to standard layout -incremental "OFF"

if { [ catch {layout} ] } { puts "Layout Failed"

export -format "log" -diagnostic $des_name.log" exit 1

} else {

puts "layout successful"

export -format log "$des_name.log" save_design "$des_name.adb"; close_design

}
