    Hi Noah,


    We have root caused the issue. A fix for this issue will be scheduled on the upcoming version.


    As a workaround for this, please remove the following line from the QSF file and rerun the full flow:

    set_instance_assignment -name PARTITION component_and_func -to "and_func:and_func_inst"


    Thanks.

Hi Noah,


So far, they had no chance to look into this yet, but one thing to confirm with you, how was this .vcd file was generated?

Also, is using other .vcd file having the same results so far from your findings?


Regards,

Aqid

    Hello again,

    I tried two ways of generating it:

    1) During the msim_run.tcl simulation script, by using the following code:

    [...]
    vcd file and_testbench.vcd
    vcd add -r /*

    run -all

    vcd flush

    [...]

    2) Generating a .wlf file as is done by default in the msim_run.tcl generated by HLS Compiler, and then using the wlf2vcd tool in the Questasim command window. The .wlf file is set to be generated in the part of the code immediately preceding the code shown above:

    [...]

    set StdArithNoWarnings 1
    set USER_DEFINED_ELAB_OPTIONS "+nowarnTFMPC -dpioutoftheblue 1 -sv_lib $fname_svlib -nodpiexports -wlf ../../vsim.wlf - voptargs=+acc"
    elab
    onfinish {stop}
    quietly set StdArithNoWarnings 1
    log -r *

    [...]

    Regards,

    Noah
