I agree that is for small designs, but seems like the only open source tool that has a flow for Verilog. I tried it for an I2C core (couple hundred gates) and it worked ok, but I have to fix DRC errors manually. I do mostly mixed-signal designs (big A small D) thus the 8k x 8k limitation is not a problem. If you have suggestions I can pass them on to Tim Edwards and see if they can be added to qrouter.

I see this thread is from 2011 but I wanted to share what I've been using for small to medium digital designs. Dr. Tim Edwards at Opencircuit has worked out a digital flow with synthesis and P&R. It has some issues but is workable and you can create a GDSII and a Verilog gate level netlist.

The synthesis flow (vl2mv, SIS) has some limitations, but I've been testing other tools like ODIN-II and QuteRTL to see which one is better.

Hello,

I'm in the process of evaluating Glade and I really like what I've seen so far. As an active IC designer I mostly rely on Cadence, but I work with other designers that use Magic VLSI which is open source. One suggestion I have is to make Glade be able to read Magic techfiles which are available through MOSIS and other websites. Below some relevant links.

Hello,

It works on Ubuntu 12.04 64-bit! Thanks.

Rgds,

No errors when I run python and it seems I do have version 2.7.3

gsuarez@geomachinex:~/cad/glade4_linux64_ub10$ python
Python 2.7.3 (default, Aug 1 2012, 05:14:39)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>>

Here's what I get for "which python".
gsuarez@geomachinex:~/cad/glade4_linux64_ub10$ which python
python is /usr/bin/python

And it seems python is just a symbolic link to python2.7
lrwxrwxrwx 1 root root 9 Nov 13 11:11 /usr/bin/python -> python2.7

Weird thing is I can see the python files

gsuarez@geomachinex:~/cad/glade4_linux64_ub10$ locate weakref.py
/usr/lib/python2.7/weakref.py
/usr/lib/python2.7/weakref.pyc

gsuarez@geomachinex:~/cad/glade4_linux64_ub10$ locate weakrefset.py/usr/lib/python2.7/_weakrefset.py
/usr/lib/python2.7/_weakrefset.pyc

I'll see if I can installed python 2.7.3. Any other ideas?

Hello,

I'm trying to install Glade on Ubuntu 12.04 64-bit. I have python 2.7 but after setting all the variables:

export GLADE_HOME=/home/gsuarez/cad/glade4_linux64_ub10
export PATH=$GLADE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$GLADE_HOME/lib:$LD_LIBRARY_PATH
export PYTHONPATH=/usr/lib/python2.7:$GLADE_HOME/bin

I still get the following, any ideas?

glade
