# Environment Setup

- Navigate to `<repo>/fpga/usrp3/top/{project}` where {project} is:
  + `x300:` For USRP X300/X310
  + `e31x:` For USRP E310
  + `e320:` For USRP E320
  + `n3xx:` For USRP N300/N310/N320
  + `x400:` For USRP X410

- To setup up the Ettus Research Xilinx build environment run
  + `source setupenv.sh` (If Vivado is installed in the default path /opt/Xilinx/Vivado) _OR_
  + `source setupenv.sh --vivado-path=<VIVADO_PATH>` (where VIVADO_PATH is a non-default installation path)

- This should not only enable building USRP FPGAs but also make available the
  utilities described in the following sections.

# ModelSim Specific

The `setupenv.sh` script will search the system for ModelSim installations and setup everything to run it natively and
within Vivado. The currently supported versions of ModelSim are PE, DE, SE, DE-64, SE-64.

The following functions are also available in the environment:

    build_simlibs: Build ModelSim simulation libraries for Vivado

# IP Management

## Create Vivado IP

## Modify existing Vivado Block Design (BD)

    viv_modify_bd: Modify an existing Vivado BD instance

    Usage: viv_modify_bd <BD File Path> <Product>
    - <BD File Path>: Path to the BD file.
    - <Product>: Product to generate IP for

## Modify existing Vivado Tcl-based Block Design

    viv_modify_tcl_bd: Modify an existing Vivado BD instance

    Usage: viv_modify_tcl_bd <Tcl File Path> <Product>
    - <Tcl File Path>: Path to the Tcl file for the block design.
    - <Product>: Product to generate IP for

## List supported Vivado IP

    viv_ls_ip: List the items in the Vivado IP catalog

    Usage: viv_ls_ip <Product>
    - <Product>: Product to generate IP for.

## Upgrade IP to the environment version of Vivado

    viv_upgrade_ip: Upgrade one or more Xilinx IP targets

    Usage: viv_upgrade_ip <IP Directory> [--recursive]
