Need help with [Designutils 20-1700] write_bitstream exception: input stream error.

Jump to solution

 

Hi,

 

I am trying to use the 10GBASE-R Ethernet in the KCU105 development kit. My current Vivado version is 2017.2 and my OS is Windows 8.1.

UG921 -  KCU105 10GBASE-R Ethernet TRD User Guide (KUCon-TRD04) ( ver2017.2, 5031 KB ) [PDF]

Describes the features and functions of the KCU105 10GBASE-R Ethernet TRD, including setup, operation, testing, and modifying the design for user applications.

Link: https://www.xilinx.com/products/boards-and-kits/kcu105.html#documentation

 

I followed the KCU105 10GBASE-R Ethernet TRD User Guide and successfully did the synthesis and implementation. However, when running Generate Bitstream, I received error [Designutils 20-1700] write_bitstream exception: input stream error.

 

Does anyone meet this problem and please let me know how to solve it. 

Thank you very much

I figured out the problem. Because the project folder path was too long, the bitstream file couldn't be generated. I moved the project to C:\ and the problem was fixed.
