通过IO路由JTAG引脚

大家好...
我发帖只是为了收集意见。
我的经理面临着一个强烈的争论，即从fpga中的IO线接收的数据可以通过相同FPGA上的JTAG引脚进行路由。
我说不......我的老板说是的。
目的是我们计划设计一个Xilinx JTAG编程器。
我说我们不能通过JTAG线路发送自定义数据......我的老板说他已经为altera JTAG Programmer做了这样的事情。
他还说，使用JTAG引脚可以大大减少编程开销。
我也有一些建议，为了充当JTAG主设备，应该使用FPGA上的IO引脚。
据我所知，JTAG引脚用于接收配置信息并响应从影响发送的命令。
我可能要知道的任何其他事情。
任何XAPP或UG都可能需要阅读。
我读过XAPP058它没有说硬件的任何东西..
请评论你的意见..

Hello everyone...

I am posting this just for collecting opinions. I am facing a strong argument from my manager that the data received from the IO lines in an fpga can be routed through JTAG Pins on the same FPGA. I say no... my boss says yes.
The purpose is that we are planning to design a Xilinx JTAG programmer.

I say that we can not send custom data through the JTAG lines... My boss says that he has done that for altera JTAG Programmer. He also says that the programming overhead reduces by a huge amount by using JTAG pins . I also got some suggestions that In order to act as a JTAG master one should use IO pins on the FPGA.

As far as I know the JTAG pins are used for receiving the configuration information and responds to the commands sent from impact. Any thing else I may have to know. any XAPP's or UG's I may have to read. I read XAPP058 It doesn't say anything about the hard ware..

Please comment your opinions on this..
