带SDF反标流程的Virtuoso AMS仿真流程指南

最近有同学问我SDF文件 怎么和AMS Flow结合起来，参阅了手册，摘录出如下流程，供有需要的同学参考。侵删，请优先参阅官方文件。

1. From ADE, navigate to Simulation > Options > AMS Simulator. 

This will pop up the AMS Options window. Click on the SDF tab from the AMS Options form. The form will look similar to this:

2. Click on the Browse button on Use SDF command file to include the file MySDF present in your current working directory. Also, from the drop-down list, select the Delay type as Maximum and enable the fields Allow unique delays for each source-delay path and Include detailed information in SDF log file as shown in the image below.

You can open the MySDF file from a terminal window to view the contents. This file specifies three compiled SDF files corresponding to your three instances (can_counter, coin_counter, and state_machine).

3.Click on the Timing tab of the AMS Options form.

Select the Delay mode as Path from the VERILOG TIMING OPTIONS section

The choices for Delay mode are Unit, Zero, Distributed, and Path. For more information on these, refer to the chapter, "Delay Mode Selection," in the Verilog-XL Reference guide.

4. From ADE, navigate to Simulation > Netlist and Run Options and make sure that the options are selected as per the figure shown below.

5. Click OK in the AMS Options form.

6. Run the simulation from ADE by selecting Simulation > Netlist and Run.
