F1.5iS2 Sim: Warning 9204: Cannot find corresponding block pin for terminal Q15.

Description

Foundation F1.5i with Service Pack 2 installed:

Starting the Functional Simulator may results in
warnings when loading the netlist as for example:

Loading - MACRO1
Loading library default timing values

Warning 9204: Cannot find corresponding block
pin for terminal Q15. Terminal will be changed to label

Warning 9204: Cannot find corresponding block pin for
terminal Q14. Terminal will be changed to label

Warning 9204: Cannot find corresponding block pin for
terminal Q13. Terminal will be changed to label

This maybe incorrect in the following case:
This macro consists of a primitive (CC16CE).
The output buspin Q[15:0] is connected to a bus named
Q[15:0]. This bus is CONNECTED with another bus named
Q[12:0]. The bus Q[12:0] is connected to a bus output terminal,
the bus Q[15:0] is not connected to any terminal.

Therefore the signals Q15, Q14 and Q13 are not connected to
a terminal, the above warnings are misleading or incorrect.




解决方案

The warnings are the result of the bus Q[15:0] and bus Q[12:0]
being connected via a bus connection. If the bus association
is done via bus naming the warnings do not occur. The physical
connection is the problem.

To resolve this warning draw the bus Q[15:0] and label it using
a bus label. Then draw the bus Q[12:0] and label it using a
bus terminal.
