Full Custom Design Flow
Layout design rules, process parameters and SPICE models are available for processes accessed by MOSIS (see layout rules).
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) scalable rules (SCMOS rules) that are not vendor-specific. These rule sets cannot be mixed within a design.
Vendor Native Rules
Use vendor-specific rules for fine-tuned layout and for those processes that support only their native layers and rule set. Foundries do not support all CAD tools. See Vendor Native-Rule Design Kits for guidence.
Users can access technology files for a variety of CAD tools (e.g. Cadence, Mentor) for vendor rules via the MOSIS secure document server for the tools listed below.
SCMOS Rules
Use SCMOS rules for portability and simplicity. See SCMOS Design Flow for CAD tools and technology files compatible with SCMOS layout rules.
Cadence
Vendor-specific process design kits (PDKs), et al., are available via the MOSIS secure document server.
Mentor Graphics
Technology files for a variety of tools are available via the MOSIS secure document server.
Silvaco
Foundry design kits are available from Silvaco.
Tanner
Tanner design kits are available via the MOSIS secure document server.
