TD conducts functional simulation with Modelsim

1 introduction

    Recently, I have been in contact with and used domestic Anlu technology company FPGA Carry out relevant development ,TD(Tang Dynasty) As an Anlu FPGA Development tools and Quartus The use is roughly the same , But there are still some differences .

2 Basic configuration process

   It is recommended to practice with the official user manual as a reference , First of all, it needs to be done TD Internal operation of software .

2.1 TD Software setting operation

    1. Process $\Rightarrow$ Properties $\Rightarrow$ Optimize RTL :

​ rtl_sim_model :ON

    2. Process $\Rightarrow$ Properties $\Rightarrow$ Optimize Gate :

​ gate_sim_model :ON

    3. Process $\Rightarrow$ Properties $\Rightarrow$ Optimize Routing :

​ phy_sim_model :ON

    4. Process $\Rightarrow$ Properties $\Rightarrow$ Timing Option :

​ sdf :ON

  5. Set relevant simulation parameters

6. function Simulation

7. Select the relevant test file （testbench file ）

There are two ways , The first is to add existing tb File to test ; The second is to create a new test file .

8. After completing the above steps, two files will be generated ：①testbench file ② Script files do file .

After these steps ,TD The setting of the software has been completed , Now we need to finish Modelsim Software settings .

2.2 Modelsim Software settings

1. First of all to enter TD The installation directory , There is a folder under the change directory as sim_release The file of , Under the folder are some simulation files of corresponding chips , Because the chip used here is EF2L45LG144B. So just copy EF2 Related files in the folder .（ Here, you must pay attention to selecting the copied folder according to the chip type ）

2. stay Modelsim Create a new folder under the installation root directory （Anlogic）, Just copy the EF2 Copy the folder into the new Anlogic >> src In the folder . here src A large number of simulation files of the chip are stored in the folder .

3. open Modelsim,File $\Rightarrow$ Change Directory $\Rightarrow$ Modify the current directory to the newly created Modelsim In the root directory Anlogic Folder .

4. File $\Rightarrow$ New $\Rightarrow$ Library $\Rightarrow$ New road safety simulation library . The library name is set to EF2_ver.

   

   

5.Compile $\Rightarrow$ Compile $\Rightarrow$ Compile new library

6. go back to TD Software , Set up Lib, Re engage Simulation.

7. take TD Under the project directory tb Documents and original Verilog Copy the file to modelsim root directory Anlogic New folder under folder , As an engineering document .

   

8. stay Modelsim Create a new project file in

9. Add test files for the project

10. Add the file and compile , Be sure to correct tb The amplitude and modification of the initial value in the file . I.e. modification initial The definition part of the statement .

11. Start the simulation , Set up the simulation file , Add simulation library

12. Simulation results
