Creating the Design Viewpoint

The design viewpoint contains a subset of the project's schematic data which is going to be used as the input data for the next tool in the design flow. For example Accusim and IC–Station needs to interpret your schematic data in different ways. IC-Station alone requires multiple input formats. Every design you create in DA must have a unique viewpoint in order to be passed on. The main reason for having DVE is in order to be able to split the design algorithm into a few different branches so different methodologies can be considered inside a single design (for example, you can describe a single block in your design in two different ways, and create two viewpoints for the whole design, each containing a different block in it so the downstream applications can evaluate the design using the two different blocks).

1. Setting the Working Directory

From the UNIX terminal, navigate to the directory where your Design Architect Schematic is located. In this case we have called the design “inv” and it should be located in your home directory, i.e. just under your user name.

disk2/acc/xxx

Where “xxx” represents your user name.

If you are not already in this directory, navigate to this directory. Set this as the working directory using the “swd” command.

2. Running the Viewpoint Script

Use the “adk_dve” script to create viewpoints for this design.

Type the command

adk_dve design_name

Where “design_name” is the name of your design, in this case we used “inv.”
