Problem Title:
SIMPRIMS: The INIT parameter is incorrectly defined for the X_LUT* Verilog models for
Alliance 1.5
Problem Description:
Urgency: Standard
General Description:
The INIT parameter is incorrectly defined in the following model
in Xilinx Alliance 1.5 toolset:
module X_LUT4 (OUT, ADR0, ADR1, ADR2, ADR3);
parameter [3:0] INIT = 4'h0;
endmodule
Solution 1:
The VMD files (located at $XILINX/verilog/data) for
the X_LUT can be modified to change the INIT:
In X_LUT4 change
parameter [3:0] INIT = 4'h0;
to
parameter [15:0] INIT = 16'h0000;
Similar changes can be made to X_LUT3 and X_LUT2
This is fixed in the Alliance 2.1i
