XABEL 5.0, XC7000 EPLD: Trouble accessing D1 and D2 alu pins


Problem Description:



Solution 1:


There is no support for the D1 and D2 inputs of an XC7000 EPLD in
XABEL 5.0. Customers wishing to explicity constrain a signal to the
D1 or D2 inputs of an EPLD high density function block must either
use PLUSASM, or define a PLUSASM PROPERTY in XABEL.  However, equations
defined by PLUSASM PROPERTY are not recognized by the XABEL compiler.
Consequently they are not simulatable and can cause errors if used in
conjunction with normal XABEL equations.
