AR# 4209
2.1i, V1.5, V1.4 COREGEN, VIEWLOGIC, FOUNDATION: symbols generated by COREGen do not match those shown in the datasheets for the core.
Description
Keywords: symbol, view, datasheet
Urgency: standard
General Description: 2.1i, V1.5, V1.4 COREGEN, VIEWLOGIC: Viewlogic symbols generated by COREGen do not match those shown in the datasheets for the core. You may notice the following:
1. The datasheet may depict a symbol consisting of a MUX and a register, for example, whereas the actual symbol generated is simply a rectangular box with pins ] attached to it.
2. The pin order on the symbol may not match the order of the pins shown in the datasheet symbol graphic.
Solution
The symbols in the datasheets are automatically generated using generic 3rd party tools from Viewlogic and Aldec, and the generation of more complex symbols is not supported by either tool. These tools also provide no control over pin order.
The symbols depicted in the COREGen datasheets should only be used as an aid to understanding the functionality of the core.
