REVISION HISTORY Readme Date Version Revision Description ========================================================================= 09AUG2012 1.0 Initial Xilinx release. 16OCT2012 1.1 Fixed typos in readme.txt file only. No changes to any other files. 17DEC2012 1.2 Made changes to the DRP controller in the SDI wrapper to insure that it correctly writes to the GTX through the DRP to change the RXCDR_CFG attribute dynamically. Created new GTX wrappers for the demos using v2.4 of the GTX wizard. Version 2.4 of the GTX wizard produces GTX wrappers with a slightly different set of ports, so the demos were updated to match the new GTX wrappers. 10JUL2014 2.0 The GTX wrappers generated by versions 3.0 and later of the transceiver wizard differ in very fundamental ways from wrappers created by earlier versions of the wizard. The SD/HD/3G-SDI core version 3.0 also has some port name changes from earlier versions of the core as required to comply with port naming standards for Xilinx IP. The SDI wrapper files have been updated to support these changes and to align the control logic and wrappers with the GTP and GTH SDI wrappers. All demo files have been updated to match these changes. VHDL versions of wrappers and demos have been removed. And, the app note now targets Vivado only. The code supplied here is compatible with Version 3.3 of the 7 Series FPGAs Transceivers Wizard that ships in Vivado 2014.2. 24JUL2014 2.1 With current Vivado synthesis, the ST 352 payload ID state machine in the SDI RX is susceptible to becoming stuck in an invalid state while the GTX RX is changing between SDI modes. The SDI wrapper has been modified to reset the SDI RX while the GTX RX is changing modes. ========================================================================= 2. OVERVIEW This readme describes how to use the files that come with XAPP592. There are two example SDI designs provided with XAPP592. One design has four SDI receivers and four SDI transmitters. The receivers and transmitters are all independent of each other. The SDI transmitters are driven by video pattern generators. The data received by the SDI receivers is captured by ChipScope Pro modules. The other design is a single channel SDI pass-through configuration where the SDI transmitter retransmits the signal received by the SDI receiver. 3. SOFTWARE TOOLS AND SYSTEM REQUIREMENTS * Vivado 2013.4 or newer 4. DESIGN FILE HIERARCHY The directory structure underneath this top-level folder is described below: \bit_files | This folder contains FPGA configuration bit files for the demos included | in this release. | \chipscope_projects | This folder contains project files for ChipScope Pro analyzer, | one .cpj file for each of the demos included in this release. | \dru | This directory contains the data recovery unit (DRU) code required | to receive 270 Mb/s SD-SDI. The dru.ngc file contains the pre- | synthesized DRU IP. It must be added to the Vivado project along with | the HDL files in the \dru directory. | +--\for_simulation_only | This directory contains a simple model of the DRU that can be | used for simulation. The dru.ngc file cannot be simulated due to | encryption of the file. The simulation model must not, however, | be used in an actual FPGA configuration because it does not have | any jitter tolerance. | \k7gtx_sdi_wrapper | This directory contains the GTX wrapper and GTXE2_COMMON wrapper files | generated by the GTX wizard specifically for these demos. | \kc705_sdi_demo | This directory contains the HDL and other files unique to the quad | SDI demo. | \kc705_sdi_pass_demo | This directory contains the HDL and other files unique to the SDI | pass-through demo. | \kc705_TEDSDI_control | This directory contains the HDL and other files that are used by | both demos to control devices on the KC705 and
