I work on the demo model hdlcoderrecon.. it opens a modelsim file automatically. Is it possible to implement the code using spartan 3 an model kit?
It is straightforward to have HDL Coder target any FPGA board that it supports. All you need to do is right-click on the desired DUT, and choose: HDL Code->HDL Workflow Advisor.
Once the Workflow Advisor opens, choose either the FPGA Turnkey or the FPGA-in-the-Loop workflow, as desired, and let the Advisor guide you through the process.
