This project aimed to support MIPI or DPI I/F off-the-shelf LCD/TFT display.

Expected FPGA Support

1. ✅ Xilinx - 7 series (Currently tested on Kintex 7 & Artix 7)

2. ✅ Xilinx - 6 series (Currently tested on Spartan 6)

3. ✅ Xilinx - Ultrascale+ / Ultrascale (Currently tested on ZYNQMP)

4. ✅ Altera - Cyclone IV (Currently tested on Cyclone IV EP4CE6F17C8)

5. ✅ Altera - Cyclone V (Currently tested on Cyclone V 5CSEBA5U19C8)

6. ✅ Anlogic - EG4 series (Currently tested on EAGLE 4 EG4X20BG256)

7. ✅ Anlogic - DR1 series (Currently tested on Dragon 1 DR1V90MEG484)

Remarks on FPGA Support

For Cyclone V, test gear is under NDA, it is sure that it can perform better than Cyclone IV.

For Cyclone V it can align with the HSTL1.8V differential pair rather than LVDS.

FPGA Support Details

a) In the follow examples, Xilinx 6 series, 7 series, ultrascale+ series should able to support as much MIPI display as possible.

b) Xilinx 6 or 7 would require resistor network to convert LVDS to SLVS.

c) Successful cases are demonstrated on three Xilinx FPGA families "Spartan", "Kintex", "Artix", and "ZYNQ Ultrascale+".

d) It is confident to say this pure Verilog-based MIPI DSI design is stabled and matured enough to merge onto any FPGA with serialization feature.

Read First !

Please study the example 5.5" LCD with LCD driver HX8399C.

This example provided detail resistor-network vs MC20902 design, which is aligned with Xilinx doc. "XAPP894".

The resistor-network is not re-simulated via IBIS simulator, so if you really concern on SI then do it as your will.

Commonly Asked Questions

1. Q: Do this design only work on Xilinx 7-series? A: There are example in Ultrascale, and other non-MIPI DSI supported FPGA brand tested internally.

2. Q: Why there are no brand xxx FPGA given? A: Because either the brand xxx either I don't have it or it is tested internally but not worth to recreate new repositories.

3. Q: Can brand xxx FPGA support 1080p, 2k, 4k etc A: If you understand how MIPI-DSI video mode works, this question won't even exist from first place!!!

4. Q: Can this Verilog-based HDL design work on brand xxxx. A: Very high chances, because the inherent design don't rely on IPs nor any DPHY, it is pure MACROs and HDL.

Remarks: there are many people asked Spartan 6 should support MIPI-DSI as well.

From experiment, it do work as expected, but why I got to buy Spartan 6 when Artix 7 is even cheaper and performs better in all aspects ❓❓❓
