Hello,

I was wondering if I can reuse the parser in a different project. Currently, the project has no license. Can you please add a license to this project specifying the permissions and the availability for reusing the project. Thanks in advance.

Hi trimcao,
Am able to parse normal lef with this module without any issues, but it is not able to parse coloured lef,
While parcing coloured lef , I am getting the following error.
It is an enhancement changes in lef.

ERROR:

Start parsing LEF file...
Traceback (most recent call last):
File "lef_parser.py", line 125, in
lef_parser.parse()
File "lef_parser.py", line 52, in parse
nextState = curState.parse_next(info)
File "/proj/ipqa_dev/sw/play/tmp_rel/lef-parser-master/lef_util.py", line 197, in parse_next
self.info["LAYER"][-1].add_rect(data)
File "/proj/ipqa_dev/sw/play/tmp_rel/lef-parser-master/lef_util.py", line 271, in add_rect
x0 = float(data[1])
ValueError: could not convert string to float: MASK

Whats new in coloured lef ..?

• MASK is a new attribute in RECT class

Example:

PORT
LAYER M1 ;
RECT MASK 1 0.038 0.035 0.074 0.205 ;
END

How to fix this issue ..?

File : lef_utils.py
The following block has to be update to resolve this issue.

def add_rect(self, data):
    x0 = float(data[1])
    y0 = float(data[2])
    x1 = float(data[3])
    y1 = float(data[4])
    points = [(x0, y0), (x1, y1)]
    rect = Rect(points)
    self.shapes.append(rect)``
