Really dumb question, but despite already taping out an IC I have forgotten how to reinstall Magic on my computer and have it linked to the SKY130 PDK. Whats the current up to date installation procedure? It seems that magic is not finding the PDK files

run magic with

-rc /pathtopdk/sky130A/magic/magic.rc

I usually start magic with

magic -T sky130A.tech -rc sky130A.magicrc

Magic only automatically links to a PDK if there is a startup script file

.magicrc

in the directory where you start magic. Otherwise, you need to specify the startup script on the command line, as Ryan and Connie said. If you want the automatic behavior, just copy the PDK startup script

sky130A.magicrc

to your working directory and rename it to

.magicrc

. @User: The

sky130.magicrc

script contains the command

tech load sky130A.tech

, so specifying a technology file on the command line is redundant.

hello @Tim Edwards, I updated (or tried to) the tools and the open_pdks local installations and I'm having the following issue: I copy the

sky130A.magicrc

file into my home directory and then try running magic, but the right bar is not loaded and I get the following errors: Could not find file 'STAGING_PATH/TECHNAME/MAGIC_CURRENT/TECHNAME-F.tech' in any of these directories: . $CAD_ROOT/magic/sys $CAD_ROOT/magic/sys/current Could not find file 'STAGING_PATH/TECHNAME/MAGIC_CURRENT/TECHNAME.tech' in any of these directories: . $CAD_ROOT/magic/sys $CAD_ROOT/magic/sys/current Error parsing user ".magicrc": couldn't read file "STAGING_PATH/TECHNAME/MAGIC_CURRENT/TECHNAME.tcl": no such file or directory any ideas what could be wrong?

The

.magicrc

file appears to be copied directly from the

sky130.magicrc

template in open_pdks, not properly installed by running

make

in open_pdks. The names like

STAGING_PATH

are template variables that get replaced during the open_pdks build.

How do i Solve this in practice?

@Jorge Marin: The solution is to clone open_pdks, then follow the instructions and run

configure

,

make

, and

make install

.

Hello @Tim Edwards, sorry, I'm not sure what I'm doing wrong I had a clone from open_pdks from around mpw4 time, so I'm going inside the cloned folder and doing "git pull" after that I'm doing configure, make and make install, and it seems to be successful, but sky130A.magicrc is not generated, please see the screenshot attached

@Jorge Marin:

configure

needs options. At least

configure --enable-sky130-pdk

.

that was it 🤦‍♂️
