I'm facing really strange problems with Arty7 Artix board. In some cases when I generate .bit file for my microblaze design, there is no locked signal from the clocking wizard. Please check attached image. Input of clocking wizard is directly connected to E3 pin and "locked" signal is connected to the one of the board's LEDs. The rest of my design is composed of MicroBlaze instance with Ethernet IP core, MIG, UART, SPI flash core and "glue" logic for these components.
I'm using Vivado 2017.2 or 2018.1, win 10 x64, win 7 x64, no matter.
Input clock is present, I have check it by using scope, seems to be OK, .xdc file is correct. No critical warnings or timing issues, nothing special in my warning list. Simply, in some cases there is no locked signal from the clocking wizard..
Any help is highly appreciated, I'm out of ideas...
