Migration Guide for Allegro Platform Products Allegro Platform Front-End Products October 2019 25 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. Design Entry CIS The following sections describe new or modified functionality that might impact existing designs or workflows in Design Entry CIS. Migrating from Release 17.2-2016 to Release 17.4-2019 This section provides details of the changes that you will observe when upgrading to 17.4- 2019. New Layout Creation This section describes the new flow for creating the physical layout from the schematic. After creating a schematic and verifying the logic by simulating the design in PSpice, the next step in the design process is to create the physical layout of the PCB board in PCB Editor; the Cadence tool for designing physical layout of a PCB board. While the actual board design tasks are performed in PCB Editor, there are a few tasks that must be performed in Capture to prepare the schematic for the layout. So after you have prepared the design for layout, you do not have to use the Create Netlist function. Instead, you need to access the New Layout option from the PCB menu. Perform the following tasks to generate the PCB Editor board file from the New Layout dialog box: 1. Select PCB – New Layout. The New Layout dialog box opens. 2. The PCB Layout Folder text box shows the name of the folder in your design directory where the *.BRD and PST*.DAT files are to be saved. For a Constraint Manager-enabled design, the zip file, pstdedb.cdsz is created instead of PST files. The default location is the directory named the last time this dialog box was invoked for the current design. If this is the first time the design is being netlisted, the default location will be an Allegro subfolder in your design directory. If the netlist files have been generated previously for the project, then the default is netlist directory of the board on which an operation was done the last time. 3. In the Input Board File text box, specify the name for an existing layout file to be used as template for generating the initial board file for the current design. This field is optional if you are creating a new board.
