Unfortunately, I met a bewildering problem with Visio-2019. I have been using Visio-2019 to make circuit drawings, everything goes well until yesterday. I modified a drawing, and generated a PDF file, after that I used a merging software to merge a set of PDF drawings into one PDF file. When I opened the collected PDF file a strange thing happens: the collected PDF file could not sh

What is the correct way to handle a PCIE request to a slow device? I have a xilinx spartan 6 PCIe using Integrated Block for PCI Express. The BAR memory map is decoded and some addresses map to fast ram, or local registers and these work OK, but some addresses map to slow devices.. like I2C or internal processes that need a few cycles to process before they can produce valid data to be ret...

Hi can anyone please tell me how to rectify this error ERROR:MapLib:30 - LOC constraint J17 on topsegF is invalid: No such site on the device. To bypass this error set the environment variable 'XIL_MAP_LOCWARN'. ERROR:MapLib:30 - LOC constraint H14 on topsegG is invalid: No such site on the device. To bypass this error set the environment variable 'XIL_MAP_LOCWARN'. ERROR:MapLib:30 - ...

Hi, I am trying to use a PMI ROM memory block in Lattice Diamond/VHDL: decoder_rom0 : pmi_rom generic map ( pmi_addr_width => 3, pmi_data_width => decoder_rom_data'length, pmi_regmode => "noreg", pmi_gsr => "disable", pmi_resetmode => "sync", pmi_optimization => "area", pmi_init_file => "i2c_decoder_rom.mem", pmi_init_file_format => "binary" )

I working on a design where there will be some five sigma-delta ADCs and several specific level detect inputs each using an LVDS input pair as a comparator. So I'm pretty committed to this working. The LVDS common mode range can work down to 50 mV and I"ll be testing that. I need to sense the voltage across a FET in an H bridge for over current or open load. The ADCs need to have decen...

I've been watching the various FPGA startup companies and a couple have pro= duct available through mainstream distributors.

I am looking for an algorithm to calculate a floating point divide. There a= re a number of options, but the one that is most clear to me and easiest to= implement on the hardware I am designing seems to be the Newton=E2=80=93Ra= phson iterative method. I'm trying to understand how many iterations it wil= l take. The formula for that in the Wikipedia article assumes an initial es= timate for...

An IPO of sorts really. They would merge with ACE Convergence Acquisition Corp NASDAQ: ACEV and this company would be seeking investors. Achronix has been profitable, so this should be a good deal. I'm looking to buy in. -- Rick C. - Get 1,000 miles of free Supercharging - Tesla referral code - https://ts.la/richard11209
