4.1i FPGA Editor - When Block Editor is used, are the "Feqn" and "Geqn" equations case-sensitive?

Description

Keywords: FPGA Editor, Feqn, Geqn, case, sensitive, Block Editor, 3.1i

Urgency: Standard

General Description:
I am trying to modify the equations for Feqn or Geqn with Block Editor -- are the equations are case-sensitive?

Solution

The equations for Feqn and Geqn are not case-sensitive; the equations are based upon a letter/number combination. Depending on the device family, the letter can either be F, G, H, or A, and the number can either be 1, 2, 3, or 4.

Use the corresponding letter/number value for the following families:

2000/3000/4000/5200/Spartan/Spartan-XL:

Feqn -> F1...F4
Geqn -> G1...G4
Heqn -> H1...H4

Virtex/Virtex-E:

Feqn -> A1...A4
Geqn -> A1...A4

This issue will be addressed in a future software release.
