Stackup Designer: Build Your COST-OPTIMIZED Build-Up Structures | Sierra Circuits

Date: 18/04/2024

Sierra Circuit's Stackup Designer enables you to quickly build cost-optimized stack-ups by considering all the signal integrity essentials. To meet the requirements of high-speed designs, the tool is integrated with a 2D field solver based impedance calculator traces. 

Some of the unique features of this Stackup Designer are:

- It provides multiple build-up options with different technology levels such as standard, HDI-1, HDI-2, HDI-3, and HDI-4.
- You can select the stack-up that best suits your requirements. If your design has a complex BGA, you just have to choose the applicable BGA pattern and enter the pin and pitch information. The Stackup Designer automatically calculates the total number of pins and the estimated number of signal pins. You can also export the layer build-up and impedance data in IPC-2581 format.

After generating the stack-ups, choose the appropriate one by clicking on report. Here in this demo, we will select the standard build-up. If your board has controlled impedance traces, you can define all the requirements in the impedance calculator section. Once the stack-up is finalized, you can export the data in IPC-2581 format.

The IPC file will be saved in export to IPC-2581 and saved in the downloads folder. To import this file into your Cadence Allegro EDA, click on cross section under setup in Allegro. Now, click on import, select IPC-2581, and hit yes.

Next, go to the downloads folder and select the IPC file. The stack-up and the impedance data are now imported into your EDA tool. Click on apply and okay to view the changes. This is one of the quickest ways to import your design files in IPC-2581 format.
