Oi Adriel!

Consegui abrir as células no Cadence, mas ao fazer o DRC dá problemas com: 
=> o tamanho mínimo de NPLUS e PPLUS que deve ser 0.6 (são os PPLUS e 
NPLUS que ficam na parte inferior do GND e superior do VDD, no final da 
célula);
=> o enclosure da VIA1 que deve ser 0.15 (deve ter uma metal 2 junto com a 
VIA1);
=> o espaço mínimo entre NDIFF (difusão N) e o NTUB deve ser de 2.6;
=> e tem em algumas células que não respeita o espaço entre metal 1 que 
deve ser de 0.45.
Obrigada!

Google recently released a manufacturable 130nm PDK which can be found at https://github.com/google/skywater-pdk and is also offering free tape outs for open source designs at https://efabless.com/open_shuttle_program

It would be interesting to see how you astran generated cells compare to the existing cells that are provided.

There is likely to be a 90nm PDK in the future too.

The README mentioned it was open source but I can find any reference to what LICENSE the source is released under?

I installed Astran for all users in our lab as a regular CAD tool. In this way, the users can use astran anywhere they are and not only from the instalation folder.

The problem with this is related to where Astran look for it own files and configurations. Take a look:

This problem is easly fixed creating a environment variable like ASTRAN_PATH, which Astran can use to search for the files. This can also be used to fix the issue #35.

That solution can also be used to improve the initial astran.cfg file like this:

set viewer "${ASTRAN_PATH}/Tools_MacIntel/wxSightGL.app/Contents/MacOS/wxSightGL"
set rotdl "${ASTRAN_PATH}/Tools_MacIntel/rotdl"
set placer "${ASTRAN_PATH}/Tools_MacIntel/mobralplace"
set lpsolve "${GUROBI_PATH}/bin/gurobi_cl"
set log history.log
set verbose_mode 1

With this solution, it is possible to change the astran lpsolver easly changin the GUROBI_PATH variable.

Please, consider to improve the astran to make it more flexible and professional with this feature. If you need help, I can try to help you with this feature.

My last astran version (3.9.8) shows:

I think you should consider to create a way sinc the github version number and the tool version number. This number is really useful to report bugs and ask for features.

Arquivo de log. Adriel, o arquivo history.log salva apenas os comandos executados né? Seria interessante colocar nele o resultado de cada comando pra facilitar o debug. O que você acha?

Existe alguma forma de setar o nome dos devices? Nossos scripts trocam todos os nomes dos dispositivos pra PMOS e NMOS, poderia ser algo assim, se não tiver. O que tu acha?

Ah, o str_Name poderia ser uma lista assim, poderia aceitar inicialmente todas as variações possiveis incluindo as variações para Vth's diferentes. E no futuro multiplos Vth's poderiam ser adicionados no layout.

SET PDEVICE <str_Name>
SET NDEVICE <str_Name>

Add a new item in the Circuit window to allow the user to change the design 
name.

Olá!

Na versão para Windows está dando problema na hora de fazer o placement ou
às vezes quando manda ele compactar o layout. O erro está em anexo.

Normalmente acontece com as células de tamanho maior, se tiver uma com
tamanho 1 e outra com tamanho 3, dá erro em todas de tamanho 3.
Por exemplo:
DFECP3, DFEP3, DFP3, DFS3, DFSC3, DFSCP3, DFSE3, DFSEC3, DFSEP3 ...
IMAJ31, IMUX21 e demais
INV4 a INV15
JK3, JKC3, JKCP3 ...
MAK32
MUX só deu certo com tamanho 1 
NAND24, 28, 32, 34, 42, 43 ...
NOR22, 23, 24 ...

Hi @aziesemer, it is possible to fix this issue?

While generating cell layout I'm getting this error at command compact layout:

Any workaround or solution?

Thanks in advance

Is it possible to still use lpsolve with astran? It seems that Gurobi is required by Astran, but for our application, an OpenSource solver is required. Would it be possible to add lpsolve support in again?
Also please document the system requirements (e.g. Gurobi) in the README.

Hi, guys.

The link to what I assume was an image of a layout generated by Astran in the README.md is broken...
https://gme-ufrgs.googlecode.com/files/screenshot2.png

Could you fix that?

It would be nice to have an image of a layout generated by Astran right there when someone accesses the GitHub page.

O Astran retorna 1 quando termina. Isso tá ok Adriel? Aqui no linux estou esperando um 0.

Hi Adriel @aziesemer ,

Thanks a lot for your excellent work! Recent Gurobi stops providing the download link of Gurobi 5.0 and now people can only find Gurobi 8.0-9.5. I am resolving the problem and a PR will be submitted.

What steps will reproduce the problem?
1. Load Netlist
2. Save Netlist

The netlist file (*.lib) loads cell's information like instances tree and
nets. However, when you save the netlist to a .lib file, this kind of
information is lost. It is not included to the file due to the data structure.

What to do:
Change the data structure to include these information in the netlist file.

Modify our spice parser to suport these netlists.

Where I can find a help with all the Astran commands?

É possivel aidicionar uma forma de ignorar comentários no arquivo de teconlogia? Isso facilita o processo de portar/modifica/adaptar esse arquivo. Normalmente ele ignora os comandos que nao entende, mas se achar o caractere de comentário, (por exemplo #) ele pode simplesmente evitar dizer essa informação na tela.

Adriel, tu já conhece o Read The Docs? É uma plataforma pra fazer documentações. O astran podia ter uma documentação lá. Toda documentação é gerada por arquivos texto como os README.md do github. Ele tem integraçào com o github tb e faz tuido automático. O bacana é que cada página é um arquivo texto com alguma tags simples. No fim, ele gera uma documentação reobusta, organizada e com um sistema de busca que facilita muito. Aqui tem um exemplo do da documentação do sublime text http://docs.sublimetext.info/en/latest/index.html. Acho interessante tu pensar nesse tipo de coisa. Que tu acha?

Show Layouts as hierarchy instead of flat in Layout list window. This will
