Question

Hi everyone a quick question I am getting these errors during `run magic spice export ` ```box 55873 307343 55907 307362 feedback add Illegal overlap types do not connect medium box 56977 307343 57011 307362 feedback add Illegal overlap types do not connect medium box 58081 307343 58115 307362 feedback add Illegal overlap types do not connect medium box 60013 307343 60047 307362 feedback add Illegal overlap types do not connect medium box 61117 307343 61151 307362 feedback add Illegal overlap types do not connect medium box 62221 307343 62255 307362 feedback add Illegal overlap types do not connect medium box 62588 307349 62612 307362 feedback add Illegal overlap types do not connect medium box 211358 306763 211362 306797 ``` There are no DRC violation during routing but the process keeps bombing at this step Any leads as to what could be the possible reason I am using magic version 8 3 176

Philipp Gühring · Answer

I have exactly the same problem did you found a solution yet

Russell Friesenhahn · Answer

I m seeing this now as well with two macros in `user project wrapper`

Russell Friesenhahn · Answer

I did a better job of manual placement of the macros using the `macro cfg` file and it finished successfully for me In the original placement macros were definitely needing to be routed around to get to IO at the wrapper level Not sure if that would cause this or not man shrugging

Aireen Amir Jalal · Answer

< Philipp Gühring> the problem solved as soon as I removed the obstructions This is bizarre though as there were no overlaps during routing

Manikandan Nagarajan · Answer

How to remove obstructions Is it allowed to do for the fabrication

Aireen Amir Jalal · Answer

I had set a `GLB RT OBS` parameter for metal5 layer in my config tcl file and commenting the variable solved the problem for me I used `GLB RT MAXLAYER` instead to avoid using metal5

Manikandan Nagarajan · Answer

I will also try thank you so much

Russell Friesenhahn · Answer

I m unfortunately seeing this trying to generate user project wrapper Any way to debug

Matt Venn · Answer

< Russell Friesenhahn> I ve just debugged this with someone else

Matt Venn · Answer

they had metal 5 in their macro

Matt Venn · Answer

must be turned off before hardening set env GLB RT MAXLAYER 5

Matt Venn · Answer

not sure why this isn t in the example project config

Matt Venn · Answer

probably the design is so small it doesn t use metal5

Manikandan Nagarajan · Answer

Yes might be not using how to turn it off

Matt Venn · Answer

set env GLB RT MAXLAYER 5

Russell Friesenhahn · Answer

I have very little met5 in my macro

Russell Friesenhahn · Answer

```grep met5 routing stc0 core def TRACKS X 1700 DO 320 STEP 3400 LAYER met5 TRACKS Y 1700 DO 323 STEP 3400 LAYER met5 + RECT met5 710 710 710 710 NEW met5 403420 620500 476100 620500 NEW met5 288420 596700 552460 596700 NEW met5 206540 583100 710700 583100 ```

Matt Venn · Answer

you need to have none I think

Matt Venn · Answer

1st thing I would try

Russell Friesenhahn · Answer

so in the macro config tcl do `set env GLB RT MAXLAYER 4`

Russell Friesenhahn · Answer

to prevent it from using met5 at all

Matt Venn · Answer

no 5

Matt Venn · Answer

the layers are off by 1 because of LI

Russell Friesenhahn · Answer

okay and I see now the default is 6 thanks that could be it must ve just luckily found that trip wire on a rebuild last night that barely pushed me over the edge

Matt Venn · Answer

yeah I ve just opened an issue on caravel user project I think it only works there because there s so much space the router by chance never uses metal5

Matt Venn · Answer

my working theory

Russell Friesenhahn · Answer

no that makes sense it won t jog up unless the cost function reaches a threshold my coarse understanding of those algorithms

Russell Friesenhahn · Answer

do you know how to translate the box coordinates so that I could ve seen this in the layout

Philipp Gühring · Answer

< Russell Friesenhahn> I developed a script to convert these but I can t find it at the moment Basically you have to divide the coordinates by 100 I think and make rect s out of it

Russell Friesenhahn · Answer

< Philipp Gühring> I will look into that next week I could ve sworn I tried that But now that I have a very clear idea what I m looking for it might make more sense Thanks and would love to see the script if you find it

Philipp Gühring · Answer

I have converted them to metal5 and appended it to the mag file and then opened the mag file in magic

Russell Friesenhahn · Answer

Thanks I ll try that

Philipp Gühring · Answer

Usage perl feedback2mag pl lt feedback txt gt gt layout mag

Philipp Gühring · Answer

Try this I couldn t find the original script anymore but that should work

Russell Friesenhahn · Answer

Thanks
