5803 - Aldec error during Post-Route Gate-Level-Timing Simulation: "SDF: Error: *_vho.sdf(19): Instance /*_tb/slice_0i not found\"
Description:
In the Aldec Simulator, an SDF error can be encountered. For example, # SDF: Error: *_vho.sdf(19): Instance /*_tb/slice_0i not found\.
Solution:
The error is mainly in the user's testbench file, not in the generated .vho and .sdf files.
The parser is for Synthesis and it cannot guarantee that all will be parsed out, which made a reason for the user to use the option "Associated Instance".
SDF is a standard delay format file which is an IEEE standard used for timing simulation only. When using SDF during simulation, the user must provide an associated instance for the SDF file under the "Associated Instance" in Simulation Wizard. Missing the target instance does not allow the SDF delay information to be applied, but the simulation still goes on without the delay.
Ex. Inst_module as defined in *_TB.vhd file.
