1. Complex Programmable Logic Device. Most CPLDs (complex programmable logic devices) have macrocells with a sum of logic function and an elective FF (flip-flop).Depending on the chip, the combinatorial logic function supports from 4 to 16 product terms with inclusive fan-in. CPLDs also differ in terms of shift registers and logic gates.

Forgive me if this is the incorrect section for this.I have a design done by an external contractor that has a Xilinx XC95144XL-10TQG100I CPLD and we are currently struggling to find a method of programming it. The contractor used Altium Designer and the Altium USB JTAG Adapter which is no longer available, and this is not a suitable production level programming solution.I attempted to download ISE Design Suite 14.7 but receive an error message ' We cannot fulfill your request as your account has failed export compliance verification.'

, I am based in Australia. We have purchased the Xilinx Platform Cable USB II but it seems you need Xilinx software to obtain the required driver.What software do people suggest for simply programming these devices that provides the driver for the Platform Cable? We have the relevant files, we just need the software that will work with this setup? Does anyone have suggestions for obtaining the ISE Design Suite software? What do others do outside the US for this?Thanks in advance, Ricky.

First, you should probably use ISE Lab Tools instead of the full ISE - Lab Tools leaves out all the stuff for building a design, and just includes what is needed to actually program the chip. As a result, it's a much smaller package.Regarding the export controls, make sure that you have all your details filled-in correctly. The Xilinx website tries automatically verify the address (it does work in Australia - I'm in Australia too) before the download, and blank/incorrect information will definitely cause it to fail. We cannot fulfill your request as your account has failed export compliance verification.' What makes this worse is that to contact support, the only way I can find is to again have this information verified before it will let me.Does anyone know of a way to contact support through a form or email that does not require this verification step or a method to talk with someone so I can complete this verification step? I find it hard to believe how difficult it is to get this simple software compared to other vendors.

It includes instructions for importing a project from ispLEVER and explains key. It is assumed you have already installed the Lattice Diamond software. From this dialog box, you can add Verilog or VHDL source files, EDIF netlist.

Okay, so we have the main Xilinx FPGA and the utility Altera MAX10 FPGA able to be programmed on the MEGA65 R2 mainboard now.That just leaves the Lattice FPGA in the keyboard to program.First step is to program the MAX10, so that can route the JTAG to the Xilinx and Lattice FPGAs. This done using the Quartus tools, but remember to hold the reset button in on the MEGA65 mainboard, as that asserts the JTAGEN line on the MAX10. The Arrow FPGA programmer module needs to be plugged in to do this. Then the normal Quartus programmer interface can be used (but remember to first have fixed the problem with the Arrow FTDI USB driver setup by following ).Actually, we simplified this by making a program.sh script, that does the programming itself - but you still have to hold the reset button in.Second step is to program the Xilinx FPGA, because our current MAX10 firmware connects the JTAG interface to the Xilinx FPGA until it asserts the FPGADONE signal, i.e., has been programmed. This requires using the TE0790 cable, and if you have the Arrow cable plugged in at the same time, you might need to run fpgajtag with the -s option to specify the serial number of the cable to uses. If that is successful, the MEGA65 will now have the friendly blue boot screen visible.That leaves the third step. Here we had a bit of fun dealing with a JTAG latency problem with the bypass through the MAX10 FPGA as well as the latency of using a conveniently long keyboard cable.

We thought about making a custom programming cable, but would prefer to keep things simple, so decided to explore how we might defeat the latency problem. Setting the 'Programming Speed Settings' in Lattice's Diamond software's programming utility managed to make it work for us, and we were then able to flash the keyboard.

It should be possible to make the keyboard flashing work via the Arrow cable instead of the TE0790, by bypassing the JTAG signals to the appropriate pins on the Arrow programmer. In fact, it should be possible to program all the FPGAs from that one interface, and even redirect the serial debugger interface there, although the serial debugger is perhaps best left where it is, so that the problem with the MAX10's programmer needing to be in the mode where it has no serial ports mapped (the root cause is a limitation in the Linux kernel with regards to having USB devices controlled by two different drivers at the same time). However, when I tried to do this, it didn't really work. So we'll just ignore that for now.What we will do, is make the JTAG bypass of the MAX10 dependent on a dip-switch, so that we can talk to either the keyboard or Xilinx FPGA as required, e.g., so that we can flash the SPI flash so that it automatically boots up on power up.

This I have now, done, so we can flash the configuration for the Xilinx FPGA as before, using a command line like./megaphone-write-flash.sh bin/mega65r2.mcsThis works even though it is the MEGAphone targeted script, because the MEGAphone and MEGA65 R2 mainboards both use the same serial flash chip for storing the configurations.But before we do that, we really need to flash our updated MAX10 bitstream, because the initial one that is there stops listening to JTAG when the Xilinx FPGA is configured. This means that we need a nice easy way to write to the flash in the MAX10 FPGA, and this turns out to not be that simple.

The MAX10 FPGAs have built-in flash, and the flashing tools don't have the means to automatically make a bitstream that allows writing to the internal flash. This is annoying, since the Xilinx tools do this really nicely, even when writing to external flash. Instead from what I can gather, you have to build a NIOS2-enabled bitstream, that also has the flash memory connected to the NIOS2 processor, so that the flashing program can instruct the NIOS2 CPU to do the flash memory accesses. This means I have to figure out how the whole IP core connection stuff in Quartus works.After talking to Antti, it turns out there is a really simple way to flash the internal flast in the MAX10: Simply program with the.pof file instead of the.sof file. This works nicely, so I have made a script flash.sh in the MAX10 repository for this.So, let's go over all of this from the top, now that we have the various tools at the ready:0.

Plug in both the TE0790 and Arrow programmers to the board.1. If Xilinx FPGA is already configured, then unconfigure it by running fpgajtag -s and pressing control-c as soon as it says 'starting to send file'.2. Hold the reset button in to put the MAX10 into JTAG mode, and run the flash.sh script to flash the MAX10 FPGA with our bitstream.3. Release the reset button, and ensure dipswitch 1 is in the off position, to select the Xilinx FPGA for JTAG bypass.4. Run./megaphone-write-flash.sh bin/mega65r2.mcs to flash the Xilinx FPGA.5.

Switch the dipswitch 1 to the on position, to select the keyboard's Lattice FPGA, and unplug the Arrow programmer's USB cable from your computer.6. Run program.sh from the keyboard cpld directory to program the keyboard.After this, all three items should be finished flashing, so that turning it off and on brings it to the same state.Now, finally, we can start trying to move forward with actually bringing up the functionality on the board.
