Prerequisites for the SDR Flow

Simulation-driven interactive routing is performed using the current of a net terminal coupled with EM reliability rules (ICT file).

The minimum set of files and data that you need to use SDR are as follows:

ICT file with EM rules (same as Voltus-Fi)
If only an ICT file is provided, SDR can run and display the maximum current passed by a wire. However, if the current of a terminal is also provided, SDR resizes the wire according to the simulation data. The terminal current extracted after simulation is generated using ADE.
Dataset
The dataset can be generated from:
- ADE-XL with Spectre
- ADE-XL with an integrated third-party simulator
  In case of a third-party simulator or no simulation information, this approach does not support Dynamic EM because only average current is captured.
.CSV file with terminal currents
The terminal current can also be initialized manually in the EAD assistant tables or imported from a .csv file. Alternatively, you can specify the terminal current directly in the EAD browser.
