Re: I need the script about m@gma flow , please someonte hel
hi,
i will give u a rough command flow for magma. it will suffice.
after u prepare volcano:
1.run fix rtl
2.say ur scan style using force dft scan style.
3.run fix netlist.
4. enter ohter scan chain constraints.
5.do run bind logical for binding ur model with library.this is not necessary if u have done high level optimization using magma.this is used only if u have netlist and do ohter things using magma.
6.define clock constraints using force timing clock.
7.define input delays using force timing delay command. for delay value see the ff delay and pad delay from lirary.
8.do the same for output using force timing check.
9.specify reset as false path.
10.run fix time and do run bind physical.
11.define pad cells using rule model and define pad cell ports to gnd or power using rule port use command and then run run prepare model pads command.
12.define io filler cells using rule model command
13.define power and gnd nets using force plan net command.
14.create vdd and vss ports using create option of force plan pad command.for other ports stitch at netlist stage.
15.then connect vdd and vss nets to supply ports of vdd and vss pads using force paln net command with cell option set to vdd and vss pad name u have specified.
16.then do floorplanning using force floorplan parameters and run floorplan apply.
17.create ur mesh.
18.create ur rail.
19.run fix cell.
20.run fix clock.
21.run fix wire.
22. check if ur constraints are met.
