kyson 0 Report post Posted December 4, 2021 I want to do a project about Xilinx FPGA Project. When I try to run my synthesis I get this error "There are no HDL sources in file set 'sources_1'. Please use the Add Sources command." - and under the messages tab i get this error. [filemgmt 20-2001] Source scanning failed (launch error) while processing fileset "sources_1" due to unrecoverable syntax error or design hierarchy issues. Recovering last known analysis of the source files. Share this post Link to post Share on other sites
