@Tim Edwards @Mitch Bailey Excuse me, when read my gds file, i found the labels appeared by large font as shown? Is there a way to reduce this font or avoid this issue, please?

Font size in GDS files is rather ambiguously explained in all the documentation I've read. I have implemented something that appears to be consistent with most GDS files I read from 3rd party vendors. What tool generated this GDS? I may need to introduce some scaling option in magic to deal with such issues if they're not resolvable any other way. Also feel free to post the GDS so I can determine if the text records could be interpreted in some way that remains consistent with how I interpret them for all other input. In addition to the bad scaling, there appears to be way too much hierarchy with way to many pins for layout this small.

@Tim Edwards Thank you for your kind reply. Please check out the attached GDS. If we can amend the recorded text, it would be better. Also, if there is a command to disappear the hierarchy circuit's labels, it would solve this issue. Thanks

@Ahmed Reda:
see no labels
will stop printing all labels, but I doubt that's what you're looking for.
@Ahmed Reda: Magic version 8.3.414 now implements a new command option
gds magscale <value>
. For the layout above, it appears that the tool that generated it (still don't know what that is) assumes that a GDS magnification of 1 = 1 centimicron (text height), while every other tool I've seen interprets a GDS magnification of 1 = 1 micron. If you compile and install magic version 8.3.414 and issue the command
gds magscale 0.1
before reading in
tg_ls.gds
, then the size of the labels looks about right. I can't really blame the tool, the GDS spec is so vague. . .

Thanks👍
