I have recently worked with several customers who were in the process of building CIMPortal equipment models for their tools. Some were using the Equipment Model Developer (EMD) which ships with CIMPortal while others were programmatically building their models using the CxModel API. Working with both sets of customers, I saw a very real need for customers to develop programming tools to create equipment models instead of relying on the EMD alone.

Every model has a unique equipment configuration. Building an equipment model through the EMD is a laborious process. Each node of the equipment is added individually with a minimal amount of automation. Although suitable for those new to CIMPortal and initial model development, the EMD is not practical for building the many unique equipment models required for every tool configuration that a manufacturer makes.

Most manufacturers use a base tool to which they can add components to meet their customer's specification. Equipment configuration data can then be imported from the bill of materials (BoM), parts inventory, or other data from the manufacturing system of record. The model builder application can import this data (from a database or spreadsheet, for example) and use the CxModel API to generate several unique equipment models automatically. The application should be able to easily generate equipment models for any tool in the manufacturer's inventory.

Developing the proper tools that meet your individual needs is the most efficient way of creating equipment models for CIMPortal. You'll save time over using the EMD and have more consistent equipment models across tools.
