Assignments

Available MAX+PLUS II Assignment Types

Specifies which of the following MAX+PLUS® II assignment types you want to import and which Quartus® II settings and configuration files are affected:

The Quartus II software and the MAX+PLUS II software formats node names and parallel pin names differently. As a result, you may want to make sure that the naming schemes map properly and don't interfere with design logic.

  Quartus II Format MAX+PLUS II Format
Node name |auto_max:auto|q0 auto_max:auto|q0
Pin name d[0], d[1], d[2] d0, d1, d2

NOTE When you import MAX+PLUS II assignments that contain node names that use numbers, such as signal0 or signal1, the Quartus II software inserts square brackets around the number, resulting in signal[0] or signal[1]. The square bracket format is legal for signals that are part of a bus, but creates illegal signal names for signals that are not part of a bus. If the design contains node names that end in a number and are not part of a bus, in order to preserve the assignment, you must edit the CSF to remove the square brackets from the node name.

The Quartus II software and the MAX+PLUS II software synthesize nodes differently. The Quartus II software may not recognize valid MAX+PLUS II node names, or may split MAX+PLUS II nodes into two different nodes. As a result, any assignments made to the synthesized nodes are not recognized during compilation.
