@Blue-moon-pix don't know if this will make difference, but looks like your using an older version of magic.

Magic 8.3 revision 50 - Compiled on Friday 19 January 2024 04:15:11 PM IST.

The current version is 8.3.460. Can you install the most recent version?

I installed recent version of magic. when I ran the make command my terminal stuck like this. I tried 3 times but still same Screenshot (443)

@Blue-moon-pix Do you need all the standard cell libraries?

volare is a quick way to download pre-built libraries if you don't need the extra hs or hdll etc libraries.

@Blue-moon-pix : I think likely the "stuck" state is still processing---Unless you have a pretty high-end, multi-core machine, the process of compiling the PDK can take a long time; if you have low memory overhead and it causes a lot of swapping, it might be a very long time. Make sure you give it at least an hour to finish, even if it's not paging. Or, you can take Mitch's advice and use volare (https://github.com/efabless/volare), which installs pre-compiled PDKs.

Got it. Thanks for the advice :)

Can i install one library at a time?

RTimothyEdwards commented 10 months ago

@Blue-moon-pix : Yes, although it's not really set up to do that conveniently. If you run configure --help you will get a list of all the libraries open_pdks knows about. Some are enabled by default and some are disabled by default. If you want to cut down the number of libraries installed, you will need to run configure with a bunch of disables for the libraries that you don't want, like --disable-sc-ms-sky130 (note that there are libraries supported for both sky130 and gf180mcu; only libraries for the PDK that has itself been enabled will be installed; so if you use --enable-sky130-pdk, for example, then you don't need to worry about disabling all of the gf180 libraries because none of them is going to be installed anyway.

I have one doubt though, if I run 'configure' with disabling low power and low speed and run 'make' to install it and again I run configure with disabling other libraries and enable low power and low speed then other libraries got deleted or its unchanged?

Ps: I have only 2 gigs of ram for my Ubuntu VM

@Blue-moon-pix : Each library is entirely self-contained, and if you generate libraries one at a time, make install will add them to whatever is already there and will not delete any libraries that were previously installed.

Alright will try that
