MicroBlaze error Synth 8-5809

I'm working on a design that will ultimately have a MicroBlaze with an Ethernet interface. I've been struggling trying to find examples, and today someone pointed me towards XAPP1026. That design seemed like a good starting point, but it was originally created in Vivado 2014.3. I started with one of the KC705 example since my SW engineer is already working with that Kintex eval board. I updated the project to 2019.1. The only significant change that I had to make was to slow the DDR3 clock down so that I could get clocks to match. UI_CLK was coming out at 150.150150 MHz which created mismatches all over. I slowed the DDR3 clock to 500 MHz since the clock dividers could generate the other needed clock frequencies from 500 MHz.

When I went to synthesize I received five of the Synth 8-5809 errors:

[Synth 8-5809] Error generated from encrypted envelope. ["c:/QD_Work/KC705_FPGA/KC705_AxiEth_150MHZ_32KB/HW/project_2.srcs/sources_1/bd/mb_subsystem/ipshared/f8c3/hdl/microblaze_v11_0_vh_rfs.vhd":112250]

Following these were three other error messages, but they are just pointing to the start of the component instanciations within the generated HDL files.

Since the microblaze_v11_0_vh_rfs.vhd is encrypted, how in the world does one go about figuring out what went wrong?

Re: MicroBlaze error Synth 8-5809

Hi @jimmeans 

Another option could be downloading Vivado 2014.3 from the archive and then follow the xapp.


Cheers

Re: MicroBlaze error Synth 8-5809

I already had 2014.3 installed, but my hope was to use the example design as a starting point for the rest of my design which will not be implemented with a 5 year old version of Vivado. Ultimately I had to recreate the example design from scratch in 2019.1.

 

FYI even in 2014.3 there was a core in the example that had to be updated.
