ADC12DJ3200QML-SP: System Verilog simulation model

Part Number: ADC12DJ3200QML-SP
Other Parts Discussed in Thread: ADC12DJ3200

I want to know whether TI has a System Verilog model of the ADC12dj3200qml-sp ADC. I want to use it for simulating my FPGA interface. All I require is the JESD204B interface section with the sampling of data to put into the JESD lanes. Thus something I can just select the JMODE and provide data samples, either randomly generated or sequential or read from file or any method to input data into the JESD interface model.

  • Hi Martin,

    The TI204c JESD FPGA IP has been created both for implementation on FPGAs (connected to TI devices) and as a simulation model. The Tx block can be used if the Rx is in FPGA and vice versa. This will enable you to use the IP to emulate the JMODEs of the ADC12DJ3200 and any of the JESD204x based TI converters. There are three things required in the case of the JMODE of interest:

    1> An edit of the LMFS parameters of the existing reference design

    2> The simulation model for the FPGA transceiver (from Vivado)

    3> An edit of the sample to lane mapping in the reference design. The tx_refdesign module implements the mapping of 16 bit samples to lane data, and this will need to be modified to match the JMODE table in the datasheet. The format of the data on the lanes is described in the IP user guide.

    In case you don't have the IP already, it can be accessed at: https://www.ti.com/tool/TI-JESD204-IP

    Kindly let us know if you have any questions regarding the configuration of the iP or the JMODE sample to lane mapping.

  • I went to the web page link provided to download the requested IP, but it asked for a form that I had to fill in for government approval for the IP. I filled in the form a week ago and have not heard anything back yet or received a link to the IP for download.

  • Hi Martin,

    Access to the IP was granted to you and you should receive an email with more information.
