9.1i EDK - "Error: (vsim-SDF-3196) Failed to find SDF file "system_tb.sdf""

Description

Keywords: simulation, ModelSim, SDF, timing, XPS, testbench

When I perform a timing simulation with the XPS-generated testbench, the following error occurs when I attempt to simulate the design:

"# vsim -sdftyp dut=system_tb.sdf -t ps system_tb_conf
# ** Error: (vsim-SDF-3196) Failed to find SDF file "system_tb.sdf".
# Error loading design
# 1"

Solution

The automatically generated "do" script is trying to load the incorrect SDF.

1. Open the "system_setup.do" file.
2. Locate "system_tb.sdf" and replace it with "system.sdf".
3. Save and close the file.

This problem has been fixed in the latest EDK 9.1i Service Pack, available at:
http://www.xilinx.com/xlnx/xil_sw_updates_home.jsp
The first service pack containing the fix is EDK 9.1i Service Pack 1.
