Let me try again with a little more detail. I can read the pads under this directory with no problem. I saved the technology file under this directory: SCN5M_DEEP.12.TSMC.tech27 and I can startup magic with "magic -w -T SCN5M_DEEP.12.TSMC". From magic's prompt, I can go ;cif istyle and see the style is "lambda=0.12(p)", so far so good. The problem occurs when I do a "cif read mTSMd025DL.cif" in that magic segfaults. I did a little research yesterday and I can see it appears unhappy before the segfault with the statements "DS 1 6 1000" indicating a scale of 6/1000 (centimicrons, I think, but perhaps millimicrons and here might be the rub). After reading and printing out errors from each and every "DS x 6 1000" statment, magic segfaults. When reading the similar gds file with "calma read , magic doesnt segfault, but does display a myriad of errors of the form "# cols doesnt divide displacement ref pt". Quitting magic ":quit" indicates there are 58 cells which have been modified, but there are no visible cells on the screen (perhaps they are 1000 times smaller then I am setup to display, or something like that). It seems to me that I am missing an invocation or a setup under magic. It should be possible to read a cif or gds file created by the Tanner L-Edit program as both tanner and magic should use similar rules for reading and writing cif and gds files. And just to make it incredibly frustrating, electric reads and displays both the cif and gds libraries just fine as downloaded from the mosis web site. > Hi, why don't you start with the README's under > > ftp://ftp.isi.edu/pub/sondeen/magic/tanner_pads_ported_to_magic/ > > altho they may be out-of-date. > > /jeff > > cfk writes: > > Gentlemen: > > I've spent a while studying the mosis cell libraries today at > > http://www.mosis.org/Technical/Designsupport/std-cell-library-scmos.html and > > downloaded both the TSMC 0.25 micron and Agilent 0.50 micron libraries.
