Simulating inferred DSP in Questa using Intel DSP simulation library

When inferring a DSP in Verilog, what is the recommended method to simulate an actual DSP from the Quartus EDA simulation library without having to create the DSP as an IP block?

I assume I need to simulate an intermediate compiled output, and I'm hoping to retain as much of the surrounding logic as possible.

This is a general question across multiple Altera FPGAs and Quartus versions, but I'm currently trying to do this with Quartus Pro, Questa Intel Starter Edition, and the C10X.

Thank you

      Hi,
      you don't need to take special prerequisites to simulate inferred (or explicitely instantiated) DSP blocks. Simply simulate your synthesizable HDL with a suitable test bench.

      Thank you for the replies and interest in my question.

      I was hoping to read that there is an established Quartus tool flow to produce an intermediate output of my inferred DSPs and memories that could be simulated in Questa using Intel simulation IP libraries along with my behavioral RTL / Verilog. This would be similar to the simulation environment if I had created the IP blocks using the IP Parameter Editor.

      No worries. I believe I can create some custom scripts to produce my desired result.

      Thank you again. You can close this one out.
