我正在尝试开发基于Xilinx ISE TCL外壳的基于Python的封装器xtclsh.exe
。如果有效,我会添加对PlanAhead或Vivado等其他shell的支持...赛灵思TCL外壳在何处发射结果?
那么,什么是大局?我有一个VHDL源文件列表,它们构成了一个IP核。我想打开一个现有的ISE项目,搜索丢失的VHDL文件并在必要时添加它们。由于IP核具有重叠的文件依赖性,因此项目可能已经包含一些文件,所以我只查找丢失的文件。
带管道的示例用户Python 3.x和subprocess
。启动xtclsh.exe
并将命令逐行发送到shell。监控输出的结果。为了简化示例,我将STDERR重定向到STDOUT。虚拟输出POC_BOUNDARY被插入到命令流中,以指示完成的命令。
附加的示例代码可以通过设置示例ISE项目来测试,该项目有一些VHDL源文件。
我的问题是显示INFO,WARNING和ERROR消息,但脚本无法读取TCL命令的结果。
手动执行search *.vhdl -type file
在xtclsh.exe结果:
% search *.vhdl -type file
D:/git/PoC/src/common/config.vhdl
D:/git/PoC/src/common/utils.vhdl
D:/git/PoC/src/common/vectors.vhdl
执行脚本的结果:
....
press ENTER for the next step
sending 'search *.vhdl -type file'
stdoutLine='POC_BOUNDARY
'
output consumed until boundary string
....
问题:
- 哪里xtclsh写?
- 如何从TCL命令中读取结果?
BTW:提示符号%
也没有给我的脚本可见。

令人难以置信!我刚刚遇到了这个问题,并且即将放弃它,因为它太过于深奥了:)现在,我可以将调试/编译信息打印到Vivado控制台!好极了! – GCon
