John,
I'd like to make some corrections to the script help file you posted on
the Downloads section of DeepChip. It is missing some double quotes and
carriage returns.
Instead of:
load dumpPLIB.scm define plibSiteName "tsm3site" dumpPLIB
/home/tsmc18/avanti/tsmc18 tsmc18.plib
it should be:
load "dumpPLIB.scm" ; {to load the Scheme code}
; {now define runtime options}
dumpPLIB "/home/tsmc18/avanti/tsmc18 tsmc18.plib" ; {to execute the
function}
and rather than specify any number of "define" commands, direct the users to
the subsequent text that shows the runtime options embedded within the
Scheme code. This script header contains 6 options:
(define plibDumpMode 2) ; 0 - technology; 1 - cell; 2 - technology + cell
(define plibBusNameRule "[%d]")
(define plibSiteName "core")
(define nameCaseSensitivity "ON")
(define maxFatWireWidth 2500)
(define debugFlag #f)
Any of these may (and some MUST) be modified by the user AFTER loading the
Scheme code. But the syntax should be corrected on your web page:
define plibDumpMode 1
define plibDumpBusNameRule "[%d]"
; ... etc....
; {and only THEN run the function:}
dumpPLIB "physLibName" "plibOutputFile"
Likewise replace:
load dumpPDEF3.scm dumpPDEF3 "tsm3site" output_pdef_file.pdef
with:
load "dumpPDEF3.scm" ; {load the Scheme code}
(define vendor "SYNOPSYS") ; {define up to 7 runtime options below}
(define program "PHYSICAL SYNTHESIS")
(define version "")
(define preRouteFormat 2) ; 0 - place obs, 1 - routing obs, 2 - pnet
; AJP set designLevel=0 for initial fp (PC deletes cell placement anyway)
(define designLevel 0) ; 0 - floorplan, 1 - floorplan + placement
; 2 - floorplan + placement + complete routing
(define debugFlag #f)
(define pdefBusNameRule "[%d]")
dumpPDEF3 "siteName" "output_pdef_file.pdef" ; {execute the function
The first Known Issue for this script is a non-issue; simply don't output
routing: define designLevel 0 or define designLevel 1 will do the trick.
Instead of:
load readPDEF3.scm.scm readPDEF3.scm input_pdef_file.pdef
use:
load "readPDEF3.scm"
readPDEF3 "input_pdef_file.pdef"
there are no runtime options for readPDEF3.scm .
Once we did all this, we found the scripts worked slicker than slick in
getting PhysOpt PDEF 3.0 in and out of Avanti PDEF 2.0. Slick!
