Any QSYS IP that is the first in the instantiation queue is failed and followed by the message about all further IPs in the queue also to be failed. In the simple test case project with only JTAG UART and On-Chip SRAM, QSYS fails on the first of these two in the queue (JTAG UART, for instance). So, no any specific component (QSYS IP) that causes this failure. And no any specific QSYS project that causes this failure. And no any specific Quartus/QSYS version(s) that causes this failure. In my opinion, something wrong with Perl Run-Time Machine that is specific for only this computer environment. Fatal Qsys error message Such message I always get each time I tried to generate a Qsys project in my computer: Info: Interconnect is inserted between master pb_dma_to_descriptor_ram.m0 and slave descriptor_memory.s1 because the master has address signal 14 bit wide, but the slave is 11 bit wide.

This is only in this computer environment, under any project and with any version of development environment (I tried from 14.0 till 20.0). What is this? how to fix that? See also screen shot. IO pins status before and during Cyclone V device power-up initialization I recognized that before Cyclone V FPGA device being initialized (immediately after power-up) there is some voltage on its IO pins (not Z-state that expected). How to prevent appearance of these parasitic signals that cause PCB problems? sof2flash error with Cyclone 10 sof file When I try to run sof2flash utility (ADS 18.1 Standard or Pro) with .sof of 10CL016YU256C8 device based project I get an error message: "foo:10A10CL016YU256C8G31/10/2019 14:50:25 - (SEVERE) sof2flash: Unrecognized device family in SOF." So I can't create xxx_hw.flashfile. Why? How to fix that?
