------- 1.6u analog pads ----------
R_40p2200_ana.mag
= protected 1.6u AMI ABN 2.2mmx2.2mm Tiny-Chip pad for use
with lambda = 0.8; this is a magic file for the 1.6u nwell
analog process, sometimes called 1.5u and a modification of 1.2u.
This is a file of 393,978 bytes
Note 1: These have Vdd! at the two top ends, pad_5 & pad_15; Vss! at the two bottom ends, pad_25 & pad_35, with also a Psubstrate contact with a ring around the inside of the chip; and Gnd! in the middle of bottom, pad_30. The outer metal2 ring is Vss, the next inner metal2 ring is Vdd; the third one in is GND and the inner most (thin) metal2 (with pdiffusion and contact) is Vss. To connect to Vdd can run metal1 to the 2nd ring or if need metal2 (for larger currents), extend the 2nd (Vdd) metal2 ring directly to pad_10. Metal2 connections to Vss can be made to the innner ring directly.Note 2: If the circuit does not have Vss but the lowest potential is at Gnd, then be sure to tie all Vss pins to Gnd so that the protection devices will be correctly biased.These correct the previous pads from the mosis magic site which have several errors but are still there [04/11/01] and include the modifications made by Dr. Dimokritos Panagiotopoulos [06/14/2001].Note 3: Be sure to use the technology file SCNA.80.tech27 with these pads, called when starting magic by: magic -T SCNA.80-------- 2.0 micron analog pads *.mag versions ---------SCNA.80.tech27 [1.6u technology; 110,933 bytes] You probably also want the following three files: SCNA.80.strm [stream file for CIF creation 548,590 bytes] SCNA.80.styles [style file of layer types; 666 bytes] SCNA.80.r [resistor calculations; 793 bytes]

_____Tiny Frame protected analog pads for MOSIS 0.5u process_____
Tiny_Frame_C05.tar.gzThese are pads, courtesy of Professor Dimokritos Panagiotopoulos, to fit on a tiny chip (1.5m x 1.5m) for the 0.5u process via MOSIS. The gzipped tar file contains the pads both in hierarchical and flat mode of Magic files as well as their CIF format. They can be uncompressed in Unix with: gunzip Tiny_Frame_C05.tar.gz followed by tar -xvf Tiny_Frame_C05.tar -- These pads should use the technology file SCN3ME_SUBM.30.tech27; thus, load via magic -T SCN3ME_SUBM.30 Tiny_Frame -- Note 1: Vdd! is the sixth pad from the right on the top and Vss! is the sixth pad from the right on the bottom. -- Note 2: The outer most and third ring from the outside are Vdd and the other two rings (2nd and 4th from the outside) are Vss.
