Cross-Referencing the Design
To cross-reference a design, you need to perform the following steps:
1. Ensure that the librarian has made the necessary changes as mentioned in Placeholder
Support on page 495.
2. Make sure that you have added ports or offpage symbols to all signals that require cross
annotation. This will ensure that cross-references assigned by CRefer will move along
with ports allowing for predictable placement in the schematic.
3. Open the schematic and perform the hier_write operation (File > Save Hierarchy)
on the schematic of the root drawing. This operation will assign the PATH property to all
the offpage symbols.
4. Close the schematic by selecting File > Exit in Concept HDL.
5. cross-reference the design.
After the design is cross-referenced, you may open Concept HDL and view cross references.
You will see that CRefer has made annotations for the entire design. CRefer has also
substituted the variable values for all custom text that includes CRefer-specific custom
variables.
The flow-chart in the Cross Referencing Flow figure on page 470 summarizes the main crossreferencing steps:
