Multiple Power Supplies for Designs

You can use the following methods to use multiple power supplies for designs

Using the ie Statement in an amsd Block for Multiple Power Supply Design: Lets you specify a supply value to apply to a library, cell, or instance in your design. You can also customize Cadence-provided connect rules. This method requires no knowledge of Verilog-AMS disciplines.

Using Block-Based Discipline Resolution for Multiple Power Supply Design: Lets you use the -setdiscipline option to tell the elaborator which discipline to apply to which design scopes.

Creating Supply-Sensitive Modules for Multiple Power Supply Designs: Lets you manage clean and accurate analog-to-digital and digital-to-analog connections in a mixed-signal design that has multiple power supplies and multiple voltages using supply-sensitive connect modules (CMs).
Inserting Interface Elements Selectively for Multiple Power Supply Designs: Lets you use the -ams_check_msup option to enable selective insertion of individual interface elements (IEs).
