installation Windows¶

Vivado 2022.2¶

Windows 64-bit: Run the settings64.bat from the Vivado/<version> directory

On Windows, click Start > All Programs > Xilinx Design Tools > Vivado 2022.2 > Vivado 2022.2 Tcl Shell to launch the Vivado Design Suite Tcl shell.

dir D:\Public\RedPitaya-FPGA
vivado -source red_pitaya_vivado_project_Z10.tcl -tclargs v0.94

We recommend Vivado 2020.1

Vivado 2020.1¶

Création d'un nouveau projet¶

Create a new project with Vivado.

Select the device xc7z010clg400-1

Add the constraint redpitaya.xdc .

Create a new Block Design

ERROR: Could not find a top module

solution Create an HDL Wrapper.

source¶

source: https://github.com/lvillasen/RedPitaya-Hello-World

Clone the repositiry

Create a new project with Vivado.

Select the device xc7z010clg400-1

Add the constraint redpitaya.xdc .

Create a new Block Design

Add the IP called ZYNQ7 Processing System from the menu and Run Block Automation with default options.

Add Module counter.v from the menu.

clic doit

Add a Binary Counter from thr Add IP menu.

Add a port called led_o with components from 7 down to 0.

connect

From the menu click on Validate Design

In 'Sources' go to 'IP Sources' right-click on 'project1' and select 'Create HDL Wraper'

Proceed to run Synthesis, Implementation and Bitstream Generation

Find the bitstream file (you may use the command 'find . -name *bit')

Transfer the bitstream file (*.bit) to the Red Pitaya (you may use *sftp root@rp-ip and put *.bit)

clic doit

Tcl Console

cd d:/Public/RedPitaya-FPGA/prj/Examples/Led_blink
source D:/Public/RedPitaya-FPGA/prj/Examples/Led_blink/make_project.tcl

pour éviter cette erreur copier le dossier core dans ../tmp/

cores.zip

Bitstream¶

le Bitstream ce trouve dans le dossier /.../RedPitaya/fpga/<project...>/<project...>.runs/impl_1

le fichier bitstream doit être remplacer le fichier /dev/xdevcfg

rp-ip 140.93.64.197

Transfer the bitstream file (*.bit) to the Red Pitaya (you may use *sftp root@rp-ip and put *.bit)

Connect to the RedPitaya (ssh root@rp-ip)

Program the FPGA with the command:
cat file_name.bit > /dev/xdevcfg

GPIO¶

Console TCL¶

utilisation des exemples

https://github.com/RedPitaya/RedPitaya-FPGA

utiliser les commandes suivante dans vivado console TCL

cd /tools/redpitaya/RedPitaya-FPGA-master/prj/Examples
source make_project.tcl

cela va ouvrir le projet complet de Led_Blink

GPIO¶

connecteur E1
exp_n_tri_io (OUT)
exp_p_tri_io (IN)

exp_n_tri_io[1.1] correspond a DIO1_N


exemple de slice pour extraire du vecteur exp_p_tri_io[7.0] le scalaire exp_p_tri_io[3.3] qui correspond au GPIO DIO3_P du connecteur E1
Slice pour démultiplexer le vecteur
Concat pour multiplexer

bidirectional¶

IOBUF¶

Utility Buffer (seulement pour les horloges)¶

https://www.xilinx.com/products/intellectual-property/util_ds_buf.html#documentation

Modification du fichier de contraite¶

### set_property PACKAGE_PIN M14 [get_ports {exp_p_tri_io[7]}]
set_property PACKAGE_PIN M15 [get_ports {exp_n_tri_io[7]}]
 ### IN
 set_property IOSTANDARD LVCMOS33 [get_ports {exp_p_in7[*]}]
 set_property SLEW FAST [get_ports {exp_p_in7[*]}]
 set_property DRIVE 8 [get_ports {exp_p_in7[*]}]
 set_property PULLTYPE PULLUP [get_ports {exp_p_in7[*]}]
 set_property PACKAGE_PIN M14 [get_ports {exp_p_in7[0]}]

FIFO¶

IP FIFO generator

OUT

Shift Register¶

Block Memory Generator¶

Clock¶

le mode auto ne détecte pas le 125MHz(FCLK_CLK0) mais semble prendre 50MHz, d'ou une erreur de x2.5 (overcloking)

parametre a modifier dans le zynq pour avoir la bonne fréquence 125MHz(FCLK_CLK0)

Bascule D flip-flop¶

util ff

PULSE¶

bascule D en mode FDCE, wizard clock 400Mhz bus par défaul 50Mhz (125MHz réel)
