Vivado HLS 2018.2中set_directive_dataflow选项报错问题

环境与背景 #

• 系统：Windows 10
• Vivado HLS版本：2018.2
• 项目：CNN的HLS实现，通过命令vivado_hls -f gen_project.tcl启动构建

触发的错误 #

执行TCL脚本时出现如下错误：

ERROR: [HLS 200-101] 'set_directive_dataflow': Unknown option '-disable_start_propagation'

后续矛盾现象 #

移除-disable_start_propagation选项后，代码运行陷入死循环，无法正常执行。

相关TCL脚本代码 #
