If pmos substrate is not connected to vdd, it will result in routing failure because M6 is reserved for power. Dirty fix is to force pins to lower metals.

I met some difficulties in the anaroute part. Could you please help me with that?
I attach a PDF file to describe my problem in detail.

I am trying to change any parameters for M1 for example from " MAGICAL/examples/mockPDK/mock.lef " but the generated layout is the same and Layout of M1 is not changed.
Kindly how can one change width, spacing, enclosure ... etc or any other parameter ?

How to reproduce: git reset --hard af681f4

Add import os to PnR.py and Router.py.

The flow somehow still fails when reading in GDS files for placer. Highly possible because of Device generator？

Dose MAGICAL support tsmc 65 nm PDK?
because there is a class for tsmc65_glovar in glovar.py.
and how can I map this tool to work with tsmc65 nm?

Rewrite the README.md. Highlight the following things.

• Now we are closer to 1.0 release. Whats' new?
• The software structure. C++ individual components and Python Magical flow.
• How to build and install the components? How to use the Magical tool as a whole.
• Instructions on running example benchmark circuits.

Currently it is file based. Adding a python interface would be concurrent with other submodules.

I run the example with python2.7, and install gdspy with pip. Then get TypeError:o_gds() takes exactly 2 arguments (3 given)

Regression tests are needed. We should work on this after having the benchmark circuits online.

Blocked by #9

Add the benchmark circuits to the repo. Remove the PDK-related parameters.

Please add the router as submodule and change the related codes if needed.

All published code should have a LICENSE file.

See https://help.github.com/en/articles/adding-a-license-to-a-repository

We need find a way to aligning pins on the top-level.

I can not find where the package device_generation is being defined. I see these imports commands:

from device_generation import *

but there is no files that exist corresponding to that package.

Suggesting to change line 220 in https://github.com/magical-eda/MAGICAL/blob/master/flow/python/Placer.py from

text = gdspy.Text(cktNode.name,50,((boundary.xLo+boundary.xHi)/2+x_offset,(boundary.yLo+boundary.yHi)/2+y_offset),layer=100)

to

text = gdspy.Label(cktNode.name,((boundary.xLo+boundary.xHi)/2+x_offset,(boundary.yLo+boundary.yHi)/2+y_offset), 'o')

This way, it creates a floorplan with readable labels in the GDS instead of labels created by multiple rectangles in layer 100. I think other users might also find it more helpful that way.

Hi, the layout of tsmc40nm pdk is used in the whole flow, so if post simulation is performed, the same pdk is required. Since I failed to find the tsmc40nm process, I would like to ask if I can change the tsmc40 to tsmc18 process in MAGICAL?

I have tried to run the following command but it gives me an error, can you help?
Command: ./build
Error: https://drive.google.com/file/d/17JOBQbn23Y62BHpwyoU4zWvw3XFfjwBK/view?usp=sharing

gcc and g++ version 8.2 are installed and I am using Debian.

We should cleaning up the hardcoded parameters.

• This would take some efforts. We should not try finishing it in a big update. But rather clean part by part.
• Because changing the codes may causing bugs, we need to do testing on them. However, we haven't built a comprehensive regression test pool yet, this cleaning up might be more suitable after we have some regression test.
• I assign this to all of the current team members. You can clean up your parts when convenient and mention this issue in the PR. But don't close this issue until it is generally resolved for the whole project.

Please add the placement engine as submodules and change the related codes. Assign to @krzhu

Hi,
I have tried to run the bench mark circuit adc1, but I am getting the following error. Could you please help me on this,? am I missing any packages or something

The layer ID is the number of layer in GDSII layout format. For example, 11 can be M1 and 12 can be M2.

The layer ID is related to know what are shapes representing for. However, we need have different strategy for different types of layers. For example, the OD layer is used in router for determining the access point. Therefore, we cannot regard them as abstract layout but need a way to know which layer is what.

This thing now involves some hardcoding and each component is managing this on their own. We need to have a unified approach to manage them.

I'm a bit confused on using SP files generated from LTSpice

When i run it im consistantly getting the same errors so matter how much simple i try to make the netlist

Bit confused on how to use my own spice files, it seems like it only works when adhering to your examples.

Hello！Magical is a good job ！ Now we want to use MAGICAL to realize the circuit designed by CSMS 250nm process, but when we change modify mock.techfile and techfile.simple in mockfile，it will report index error just as below.
May I ask whether MAGICAL supports modification for 250nm or how can we modify according to your two file examples, please give some suggestions，thank you very much! BEST WISHES!

Please add submodules of constraint generation and device generation to the master branch. And change the corresponding codes in the flow.

THe latest version of MAGICAL (VERSION-0.5 apparently) is missing a Include.mk file.
Running make at top level fails with the error message :
Makefile:10: /home/ronan/perso/github/MAGICAL-v0.5/Include.mk: No such file or directory

Is it because the device attribute unit is not recognized?
At the same time, I would like to ask how to run the exported high-hierarchy netlist. Is it need to modify the netlist format?
Thanks!

I get the following error:

I am using a simple custom circuit and the PDK files are all the mock files provided in the GitHub. I am not sure what this error is exactly. Please help!

Have you considered using the new SkyWater PDK released by Google? There is an free (as in beer) shuttle for free (as in freedom) designs coming up in november and multiple more next year.

The analog primitive spice models should be released real soon and you can contact me at either [email protected] or [email protected] if you want to get early access to them. Otherwise sign up to the announcement mailing list and/or join the slack channel to be informed when they are publically available.

You can see the start of the public documentation around the analog models in the draft pull request at google/skywater-pdk#136 and https://skywater-pdk--136.org.readthedocs.build/en/136/rules/device-details.html

Looking forward to seeing what you can do!
