AR# 1903: Foundation Simulator - Unknown outputs on XBLOX or VHDL designs
Foundation Simulator - Unknown outputs on XBLOX or VHDL designs
Keywords: simulate, unknown, XBLOX, VHDL
General Description: During functional simulation, the outputs of an XBLOX component--or a VHDL macro containing inferred XBLOX components--are unknown.
This can happen if XBLOX is not being run prior to simulation. The Project Manager may not detect the need to run an XBLOX update. If this happens, the simulation netlist will contain XBLOX components that are not simulatable.
To force an XBLOX update, delete the <design>.alb and <design>.asx files, and run the functional simulation again.
