Vendor and MOSIS SCMOS Design Rules
Projects submitted to MOSIS for fabrication can be designed using either vendor-independent, scalable rules (MOSIS SCMOS Rules), or design rules specific to a process.

Projects submitted to MOSIS for fabrication can be designed using either vendor-independent, scalable rules (MOSIS SCMOS Rules), or design rules specific to a process.
Projects submitted to MOSIS for fabrication can be designed using either layout design rules specific to a process (vendor native rules) or (for some processes) vendor-independent, scalable rules (SCMOS rules). These rule sets cannot be mixed within a design.
Use SCMOS rules for portability and simplicity. Use vendor specific rules for fine-tuned layout.
Vendors consider their rules, process specifications, and SPICE parameters proprietary and make them available to MOSIS commercial account holders in different ways.
MOSIS Scalable CMOS (SCMOS) is a set of logical layers together with their design rules, which provide a nearly process- and metric-independent interface to many CMOS fabrication processes available through MOSIS.
