Description

General Description:

When running "modelsim.do" in the <PCI_CORE Install Directory>/vhdl/example/func_sim in ModelSim, I receive the following errors:

"ERROR.. - dumtarget32.vhdl (138) - assert program 2 std_logic vector is ambiguous."

"ERROR.. - dumtarget32.vhdl (197) - assert program 2 std_logic vector is ambiguous."

Solution

To resolve this issue, use the -87 switch when running the vcom command:

vcom -explicit -f ping.files

to

vcom -87 -explicit -f ping.files
