Xilinx encourages the following design flow for incorporating serial transceivers into a design:
| (Xilinx Answer 57259) | Creating the HSSIO with the Wizard | Every HSSIO design should be started by using the appropriate wizard to create an example design approximating the intended functionality of the link. Details on how to select appropriate settings are given in this answer record, the wizard user guide, and the transceiver user guide. |
| (Xilinx Answer 57260) | Design Implementation | Once suitable IP has been generated by the wizard, it should then be used to create an example design and incorporated into the actual design logic it is meant for. Some modifications might be necessary, but the vast majority of MGT settings should be left to the wizard. This answer record contains guidance on going through this process. |
| (Xilinx Answer 57261) | Digital Simulation | Along with the example design, the transceiver wizard provides wrappers around a digital simulation model of the transceiver. This can be used to accurately simulate the transceiver bring-up, resets, and interaction with user logic. Digital simulation should be performed to verify the behavior of the transceiver in your design. |
| (Xilinx Answer 57191) | Electrical Simulation | Electrical simulation pertains to verifying the integrity of your physical link. Signal integrity can be simulated using Xilinx-provided IBIS-AMI models. Details on how to perform your own simulations are given in this answer record. |
| (Xilinx Answer 57237) | Debugging | When a transceiver design is not working as intended, there are many factors to consider when looking for a solution. This answer record will help guide you in that process. |
This answer record contains a list of all of the documentation that is relevant to High Speed Serial Applications using the Xilinx Multi-Gigabit Transceivers.
It includes user guides, data sheets, errata with transceiver-related items, application notes, and white papers.
