Using insert_pads command in DC

[sam536]

Does any one worked on DC with insert_pads command?. It looks like obsolete in 2007.03. Any comments...

By the way i want to insert io pads at netlsit level. I welcome all your inputs/examples/scripts if you can support me...

i need help in jtag insertion and BSD usage. If any one worked on this, pls let me know,..New to Boundary scan insertion..

Regards,
Sam

dc_shell insert_pads

Now IO pad will be added in layout's software if I am not wrong.

In the past, we extract digital circuit then place IO pads in some layout software. Thus DC's insert_pad has never been useful.

Hai Dude,

Try this comments

link-library=target_library=sc-cadence.db)---- depends on the tool
read-f VHDL.rtl/arbiter.vhd--------- Depends if u use verilog
set_port_is pad
insert pads
verilog out_single
-bit=true
write-f verilog-output gste/arbiter op.v
quit

hi every body, I have a question:

why insert pad in dc? why not instantialized them in your top level design?

Modify your RTL and insert pads there and link the library. That is more better and effective way as u dont wanna optimize it, rather for constraining and analyzing the design

I think that PADs are always instantiated by hands in Verilog Coding.

IN DC-FPGA, you can use
set_port_is_pad ...
to automatically insert PADs.
