insert_buffer

[AayushiRV]

I am inserting buffers to my design. How can I find that buffers are being inserted? I cannot find anything in my design's netlist.

How are you inserting the buffers?

[AayushiRV]

I am using "insert_buffer" command.

Am I doing anything wrong?

[vijayank88]

Where you got reference for above format?

[AayushiRV]

I got confused, it must be there in older version.

[maliberty]

There is no such command in OR:

openroad> insert_buffer
invalid command name "insert_buffer"
while evaluating insert_buffer

[vijayank88]

Which flow you're using OpenROAD-flow-scripts or OpenLane?

[AayushiRV]

OpenLane

[vijayank88]

Are you using latest OpenLane?

[AayushiRV]

Placement and routing for my design is not working in the latest version of OpenLane, I had already discussed it here-
The-OpenROAD-Project/OpenLane#1911 (comment)
So I am working with the older version.

[vijayank88]

Added my comment there. Try to resolve and then run the flow.
As per The-OpenROAD-Project/OpenLane#1685 PR ECO flow removed from OpenLane, so what ever you're trying its lead to an bug.

@AayushiRV
insert_buffer is maintained by OpenLane. Check this example: https://github.com/The-OpenROAD-Project/OpenLane/blob/master/tests/1007/interactive.tcl
So OpenROAD nothing to do with that.
