  1. Hello all, some months ago I had a Basys 2 Board that I perfectly could program via multisim, designing an schematic and then exporting the design. Now I have an Arty S7 on my hands and I would wish to do the same. I followed the tutorials: http://www.ni.com/tutorial/14871/en/ and https://reference.digilentinc.com/learn/programmable-logic/tutorials/program_fpgas_through_multisim/start An instance for the Arty S7 was created in multisim and it gave me the option to generate the VHDL file from the design (I haven't verified the file yet). Multisim won't give me the programming option. I checked the configuration files for others working boards and there is a missing line for programming, like Device ID etc. Mi question, does anybody has tested programming the arty s7 from multisim? if not is it possible? directions ? Best Regards, Edwin Marte
  2. Dear Zygot I am just updating about my case. Sometimes we need a little push from somebody else or even leaving the project for a few hours or days. I tried to calm down as I was getting to the panic state just becasue nothing was working as it was supposed to do. I read carefully your message, although what you told me is what I do anyways, I tried to be open mind, So I started from scratch, testing the simple I/O, testing the Simple hello world and changing bit by bit. I am really not sure What I was missing or what I was doing wrong but my system is back on again. I am so happy Now! I spent like a week, even thinking during the night, what could have been the reason? what can I do different ? But anyways, I will post later on with updates of the project. cheers!
  3. Thanks Zygot! I am checking! I would think I did all that but I will slowly check all again as you mention. I will wait for anybody reply that may bring some light. Thanks for taking the time. Edwin
  4. Hello All! I have a Arty S7-50 Rev B Board. I am trying to control a mobile robot . I am also using a camera and to talk to both of them I need either I2c or serial communication. So far I created my system using microblaze with no problem. I tested leds, buttons, uart communication etc. My problem comes when I try to map pins other than buttons, leds or switch. I haven't been able to put the system to work. I Tried testing all I could think of before coming to the forums. I saved the project as another one, Created a new one from scratch etc etc and nothing so far. It have been many days if not weeks working in this part. I am pretty confidence about my design and about what I have to do with the robot. What I can't not is get signals out. So at this moment I'll give you some print screen of what I have. I could have some mistakes but it have been a lot of copy and paste and change so I got nowhere to go. I hope some of you could point me on where or how to go. I have this system with all this IP but at the beginning I was testing one by one. I need wither 2 uartlite o 1 I2c working. I know the microblaze, gpio0, timer and interrupt is working. Constraints: I had played a lot with this, this is the las I got. ## Switches set_property -dict { PACKAGE_PIN H14 IOSTANDARD LVCMOS33 } [get_ports { sw[0] }]; #IO_L20N_T3_A19_15 Sch=sw[0] set_property -dict { PACKAGE_PIN H18 IOSTANDARD LVCMOS33 } [get_ports { sw[1] }]; #IO_L21P_T3_DQS_15 Sch=sw[1] set_property -dict { PACKAGE_PIN G18 IOSTANDARD LVCMOS33 } [get_ports { sw[2] }]; #IO_L21N_T3_DQS_A18_15 Sch=sw[2] set_property -dict { PACKAGE_PIN M5 IOSTANDARD SSTL135 } [get_ports { sw[3] }]; #IO_L6N_T0_VREF_34 Sch=sw[3] ## Buttons set_property -dict { PACKAGE_PIN G15 IOSTANDARD LVCMOS33 } [get_ports { btn[0] }]; #IO_L18N_T2_A23_15 Sch=btn[0] set_property -dict { PACKAGE_PIN K16 IOSTANDARD LVCMOS33 } [get_ports { btn[1] }]; #IO_L19P_T3_A22_15 Sch=btn[1] set_property -dict { PACKAGE_PIN J16 IOSTANDARD LVCMOS33 } [get_ports { btn[2] }]; #IO_L19N_T3_A21_VREF_15 Sch=btn[2] set_property -dict { PACKAGE_PIN H13 IOSTANDARD LVCMOS33 } [get_ports { btn[3] }]; #IO_L20P_T3_A20_15 Sch=btn[3] ## Pmod Header JA #//set_property -dict { PACKAGE_PIN L17 IOSTANDARD LVCMOS33 } [get_ports { jap }]; #IO_L4P_T0_D04_14 Sch=ja_p[1] set_property -dict { PACKAGE_PIN L17 IOSTANDARD LVCMOS33 } [get_ports { led2 }]; #IO_L4P_T0_D04_14 Sch=ja_p[1] ## Pmod Header JD ##//set_property -dict { PACKAGE_PIN V15 IOSTANDARD LVCMOS33 } [get_ports { jap }]; #IO_L20N_T3_A07_D23_14 Sch=jd1/ck_io[33] set_property -dict { PACKAGE_PIN T13 IOSTANDARD LVCMOS33 } [get_ports { tx_1 }]; #IO_L21P_T3_DQS_14 Sch=jd2/ck_io[32] set_property -dict { PACKAGE_PIN R11 IOSTANDARD LVCMOS33 } [get_ports { rx_1 }]; #IO_L21N_T3_DQS_A06_D22_14 Sch=jd3/ck_io[31] set_property -dict { PACKAGE_PIN T11 IOSTANDARD LVCMOS33 } [get_ports { tx_0 }]; #IO_L23N_T3_A02_D18_14 Sch=jd9/ck_io[27] set_property -dict { PACKAGE_PIN U11 IOSTANDARD LVCMOS33 } [get_ports { rx_0 }]; #IO_L24P_T3_A01_D17_14 Sch=jd10/ck_io[26] set_property -dict { PACKAGE_PIN V15 IOSTANDARD LVCMOS33 } [get_ports { leds[0] }]; #IO_L16N_T2_A27_15 Sch=led[2] set_property -dict { PACKAGE_PIN U12 IOSTANDARD LVCMOS33 } [get_ports { leds[1] }]; #IO_L17P_T2_A26_15 Sch=led[3] set_property -dict { PACKAGE_PIN V13 IOSTANDARD LVCMOS33 } [get_ports { leds[2] }]; #IO_L17N_T2_A25_15 Sch=led[4] set_property -dict { PACKAGE_PIN T12 IOSTANDARD LVCMOS33 } [get_ports { leds[3] }]; #IO_L18P_T2_A24_15 Sch=led[5] ## USB-UART Interface set_property -dict { PACKAGE_PIN R12 IOSTANDARD LVCMOS33 } [get_ports { uart_rxd_out }]; #IO_25_14 Sch=uart_rxd_out set_property -dict { PACKAGE_PIN V12 IOSTANDARD LVCMOS33 } [get_ports { uart_txd_in }]; #IO_L24N_T3_A00_D16_14 Sch=uart_txd_in ## ChipKit I2C set_property -dict { PACKAGE_PIN J14 IOSTANDARD LVCMOS33 } [get_ports { ck_scl }]; #IO_L24N_T3_RS0_15 Sch=ck_scl set_property -dict { PACKAGE_PIN J13 IOSTANDARD LVCMOS33 } [get_ports { ck_sda }]; #IO_L24P_T3_RS1_15 Sch=ck_sda ## Configuration options, can be used for all designs set_property BITSTREAM.CONFIG.CONFIGRATE 50 [current_design] set_property CONFIG_VOLTAGE 3.3 [current_design] set_property CFGBVS VCCO [current_design] set_property BITSTREAM.CONFIG.SPI_BUSWIDTH 4 [current_design] set_property CONFIG_MODE SPIx4 [current_design] ## SW3 is assigned to a pin M5 in the 1.35v bank.

I/O Pots on Schematic I/O Ports on Synthesized Design Code of Sliding LEDS using timer on LEDS: This is funny, these are some sliding leds. It does not matter where I put / map this pins on contraints, this always light the leds. I was tring to map this in pmod header JD but it just ligh the leds. Serial Test: Here the USB serial workf fine with the PC but the other 2 are sending nothing. I2C selftest. The selftest failed, I know it fails on XIic_SelfTest This board is brand new, I only have it for a few weeks. I havent connected anything to the ports. I measured pins either with a tester or with a analog discovery so not short ciruits or similar have been produced. Any help would be apreciated. Edwin
  5. Hello Again, I was able to generate a changing signal like the image above. I used 3 sweep intervals and external and It does the job. It is not ideal but it works. I tested it with a simple low pass RC filter now I have to test it with a real power supply.
  6. I Understand. Definenily that feature would be a great plus to the Waveform. For now I have been doing some testing with a mixture of tips I have been reading from where you in most of them actually. What I I think it may work is using The ADD Channel option (limited to 8). 1-) Back to your example, lets say that we sweep 1Volt amplitude from 100Hz to 1kHz and then Save in Add Channel 2-) Then from lets say from 100khz to what... 250k a 250mV fixed. 3-) And then a Third sweep from 1Khz to 100KHZ using External and waveform to generate a sweep (in sweep option) from 1k to 100khz with an amplitude of 1V damping option to 250mv. 1 and 2 can and could be done easily. Getting to generate in waveform the middle interval is being my problem so far. It is no a perfect solution but I think once we can generate the sweep we want we could get satisfactory responses. Pretty much like image below. I already have a isolation transformer I got from ebay and also I will be building in the next week a kit for measuring output impedance in power supplies. I am trying to replicate Ridley Ap300 accessories. Well, I'll keep you posted of any updates. Regards, Edwin
  7. I see ! Thanks Attila. I will have to thibk of somethng else for the time being. (My custom board maybe)
  8. Thanks Attila, at first it seems to me that option did not work but I was just trying very light test. I'll keep trying this weekend and I''ll let know you know the results. Edwin
  9. Achmed,did you find any work around to this? I have been trying the same with no luck yet.
  10. Or are they any workaound for those like me trying to use the BNC board with diferential inputs.?
  11. Anyone has information on BNC Board Gerber/Schematics ? I would like to make Board modifications if possible, in order to brake the shorts between grounds. Edwin
