Dear Support, I am trying to implement a Microblaze in the Arty S7 with 50T FPGA board revision E. (yes Rev E not B). I instantiate GPIOs, Switches, LEDs, pushbuttons, UART and SPI at J7. I want to write c code to control the LEDs and talk to an SPI device. Attached is my implementation in picture format. The design verifies, synthesizes, and implements, but I get timing is negative. ISSUES 1. I am not sure how the GPIOs route from the block diagram to constraint file. I downloaded the constraint file, and uncomment the clock, and GPIO switches, etc...However, in the blo
I purchased a Nexys-Video and implemented a Microblaze based project on it by following a tutorial on Digilent's website https://reference.digilentinc.com/nexys-video:gsmb?do= Before I started I made sure I got the latest set of board files from the digilent website. I followed the instructions as indicated, although I noticed that there were some inconsistencies in the tutorial as in some screens hinted that the tutorial was written originally for the Nexys4DDR and was later adapted for the Nexys-Video board (some screens still show Nexys4DDR). I tried pasting here a picture
