# LiteX UART DDR minitest
|
||||||
|
|
||||||
|
This test aims at providing a minimal DDR design.
|
||||||
|
The design is tested with a python script that provides memory control signals to the DDR controller
|
||||||
|
using an UART bridge.
|
||||||
|
|
||||||
|
The script performs the calbiration process, therfore it looks for the bitslip as well as the delay values.
|
||||||
|
|
||||||
|
### Litex environment
|
||||||
|
|
||||||
|
The litex module used is LiteDRAM, which should be checked-out at the correct commit:

|
||||||
|
|
||||||
|
|
||||||
|
### Implementation
|
||||||
|
|
||||||
|
There are two different ways to test this design:
|
||||||
|
|
||||||
|
1. Vivado: the flow is entirely managed by Vivado, including Synthesis. To make use of this flow do the following:
|
||||||
|
|
||||||
|
```
|
||||||
|
cd src.vivado
|
||||||
|
make
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Yosys + Vivado: the flow is divided in two steps. Yosys handles synthesys, while Vivado handles P&R and bitstream generation. To make use of this flow do the following:
|
||||||
|
|
||||||
|
```
|
||||||
|
cd src.yosys
|
||||||
|
make
|
||||||
|
```
|
||||||
|
|
||||||
|
### Testing
|
||||||
|
|
||||||
|
To test the implemented design, load the bitstream produced in the previous step, and do the following:
|
||||||
|
|
||||||
|
1. Open the litex server:
|
||||||
|
|
||||||
|
```
|
||||||
|
lxserver --uart --uart-port=/dev/ttyUSBX
|
||||||
|
```
|
||||||
|
|
||||||
|
2. On a different terminal, connect to the server through the client script
|
||||||
|
```
|
||||||
|
cd scripts
|
||||||
|
make test_sdram
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Output
|
||||||
|
|
||||||
|
Depending on the clock frequency selected during the gateware generation, different outputs are generated:
|
||||||
|
|
||||||
|
- 50 MHz sysytem clock:
|
||||||
|
|
||||||
