EDMD Schema Design Data Cycle
The EDMD Schema Design cycle consists of three phases:
■ Creating initial baseline
■ Incremental modifications
■ Final baseline synchronization.
The exchange flow contains two files, the data file, which contains the object data, and the
transaction files.
MCAD to Allegro with MCAD Baseline Initiation
This section describes the creation of the baseline from the MCAD tool, which is then passed
to Allegro PCB Editor for import. Key components (with assigned reference designators) are
placed in the Allegro drawing and an incremental IDX file exported from Allegro to the MCAD
tool. The key components exported to the IDX file are imported, and then placed in proper
locations by the MCAD designer. A new incremental IDX file with the updated placement is
passed back to Allegro for import.
