A DSP48E1 program was designed with Xilinx's primitive module, and modelsim was used to simulate it. The compilation is correct, and an error is prompted during simulation:
# ** Error: (vsim-3033) D:/program/PQ/src/rms_macc.v(144): Instantiation of'DSP48E1' failed. The design unit was not found.
#
# Region: /tb_rms_meter/uut/inst_rms_macc
# Searched libraries:
# D:/program/PQ/modelsim/work
# Error loading design
The FPGA model used: xc7k325tffg900-2; software tool: Vivado 2014.2 + modeltech64_10.2c; the code is verilog.
It seems that the library of xilinx primitives was not found. But I have compiled the xilinx library before using modelsim.
How can I make modelsim simulate the xilinx primitive module?
