You can enter one of the following values: Vcci Voltage vcci Sets the input/output supply voltage. Refer to the datasheet for your device to determine how many banks it has.
The number of I/O banks varies with the device. I/O banks are numbered 0 through N (bank0, bank1.bankN). Set_iobank -bank_name \ \ \ \ Īrguments -bank_name Specifies the name of the bank. Each bank type supports a different set of I/O standards as listed in the Table below. There are two types of I/O banks: General-Purpose IO (GPIO) and High-Speed IO (HSIO). All banks have a dedicated vref pin and you do not need to set any pin on these banks. Set_iobank PDC command sets the input/output supply voltage (vcci) and the input reference voltage (vref) for the specified I/O bank. Supported Families This User Guide covers the PDC commands applicable to the PolarFire devices.Ģ – I/O PDC commands I/O PDC commands are used to set and reset I/O standards, voltages values, and attributes. These PDC commands can be used as part of a script file to constrain the Place and Route step of your design.
When changes are made in the I/O Attribute Editor or the Chip Planner, the PDC file(s) are updated to reflect the changes. The I/O Attribute Editor is the interactive tool for making I/O attributes changes and the Chip Planner is the interactive tool for making floorplanning changes. PDC commands can also be generated by the Libero SoC interactive tools. You can enter PDC commands manually using the Libero SoC Text Editor. Physical design constraints (PDC) are used to constrain the I/Os attributes, placement, and routing during the physical layout phase. PDC Commands - Introduction In the FPGA design world, constraint files are as important as design source files.
