The update_macro
command adds leaf cells and relative placements
(RLOCs) to the macro.
The RLOC has identical syntax and functionality as the RPM RLOC attribute. All cells must be specified at once. No partial or incremental definition is allowed.
update_macro Syntax
update_macro [-absolute_grid] <macro name> <cell-RLOC list>
where
-
-absolute_grid
: A switch to choose the Absolute Grid for mixing slice and non-slice sites.- The X-Y values are the site properties RPM_X and RPM_Y.
- The Absolute Grid values are identical to those of RPM_GRID.
- macro name: The name of the macro to be updated.
- cell-RLOC list: A Tcl list of cells and RLOC
pairs:
{cell0 RLOC(cell0) cell1 RLOC(cell1) - cellN RLOC(cellN)}.
- All macro cells and RLOCs must be specified at once. It is not possible to build a macro in steps.
- If you need to update an existing macro, you must re-create it first.
update_macro Example One
update_macro m1 {u2/sr0 X0Y0 u2/sr1 X0Y1}
- Adds
u2/sr0
andu2/sr1
to macrom1
- Assigns
u2/sr0
an RLOC ofX0Y0
- Assigns
u2/sr1
an RLOC ofX0Y1
The following (update_macro
Example Two) does the same, with
slightly different syntax.
update_macro Example Two
set rlocs [list u2/sr0 X0Y0 u2/sr1 X0Y1]
update_macro m1 $rlocs
update_macro Example Three
This example uses the absolute grid:
set rlocs {ireg X2Y38 q1reg X17Y40 q2reg X17Y40}
update_macro -absolute_grid m2 $rlocs
