I have been working this morning with Graham's library and I have a couple of observations and a couple of questions. The first observation is that in working with his cell iv1v0x05.mag which is the smallest and simplest cell. I seem to have DRC errors for "metal1 width" and "metal1 spacing". These are mosis rules 7.1 and 7.2. I am using two different technology files. The first is "SCN5M_DEEP.12.tech27" and the second one is "SCN6M_DEEP.09.tech27". These are the .25um and .18um tech files, that near as I can tell are most appropriate for .25um and .28um designs at this time. They both say the metal1 spacing and metal1 widths need to be 3 lambda and they are 2 lambda in the cells themselves. I cant tell if this is a cell issue or a technology file issue and would appreciate some guidance. My questions relate to the technology files themselves. 1. Is "Is SCN5M_DEEP.12.tech27" the appropriate technology file for .25um studies?" 2. Is "Is SCN6M_DEEP.09.tech27" the appropriate technology file for .18um studies?" 3. What is the appropriate technology file for .13um studies? 4. What is the appropriate technology file for .09um studies? I want to comment Graham for his effort to get as far as he has. I think trying to create a library that is scalable between .25um, .18um, .13um and .09um is a marvelous thing and I want to understand and help as much as possible.
