Actually, I take that back: at around the 0:27 mark, there are a couple of video frames where the log window shows

[ERROR ORD-0003] 0 does not exist.
ORD-0003

Looks like '0' is the uninitialized name of something, just need to figure out what

ORD-0003

is referring to...

Looks like you ran something like:

read_def 0

The error code is for when the def file does not exist

Hi Vitor, if I run

flow.tcl

without the

-gui

flag, then it looks like I get a full run of the tool (I see a lot of

[STEP <nn>]

log entries, starting at

[STEP 1]

and ending at

[STEP 43]

At the end, it says

[SUCCESS]: Flow complete.

@Vijayan Krishnan do you have more experience on the gui with OL?

I see in prep: if { ! [info exists ::env(CURRENT_DEF)] } { set ::env(CURRENT_DEF) 0 So perhaps the CURRENT_DEF isn't found and then gui.tcl does: if {[catch {read_def $::env(CURRENT_DEF)} errmsg]} { puts stderr $errmsg exit 1 }

Hi Matt, I was looking into this myself yesterday and I think these missing env vars may be causing the issue. I'm still not 100% on this approach, but I tried running

flow.tcl

under

strace

like so:

$ strace -s 10000 -f flow.tcl -gui 2> log.stderr

And within

log.stderr

, I eventually found the following entry:

[pid   460] execve("/build//bin/openroad", ["openroad", "-gui", "/openlane/scripts/openroad/gui.tcl"], 0x2900480 /* 368 vars */ <unfinished ...>

which I think is the

openroad

invocation string - If I try to do this manually from a `$ make mount`'ed OpenLane container, I get the following on the terminal

OpenLane Container (c0be543):/openlane$ /build//bin/openroad -gui /openlane/scripts/openroad/gui.tcl

can't read "::env(MERGED_LEF)": no such variable

One thing I haven't figured out yet is where those environment variables get set

after running 'make test' I did a 'make mount' and then ./flow.tcl -design spm -tag openlane_test -gui this opens fine for me. Does this work for you?

Yes! that worked! I was literally just doing

$ flow.tcl -gui

I thought for some reason, that if i ran it from the

designs/spm

directory, then it would automagically load the

spm

design. Thanks!
