vcs simulation scripts generation

I have the atan IP as part of my quartus project. The IP simulation script generated for vcs doesn't use any atan.vho file. It uses the atan.vhd file (same for mentor, cadence). I also see atan.vhd...

Hi,

If I try with Questa Intel FPGA Edition I get the simulation .do file generated (simulation/modelsim/*msim_rtl_vhdl.do) without any errors.

However in the .do file I see the reference to the same .vho missing files, so the design cannot be compiled/simulated.

vcom -93 -work work {/<path>/ip_atan/atan.vho}

vcom -93 -work work {/<path>/ip_spfp2dpfp/conv_spfp2dpfp.vho}

So, I get the same results as in the vcs flow, but one step later, when I acutally run the .do file and not when it's generated.

The question remains the same, why the standalone simulation scripts of the IPs don't need the .vho files, but the full design's simulation script is looking for these files?

Thank you.
