BSCANE2 documentation?

JTAG user access via the BSCAN component for Spartan 6/Virtex 6 is documented in their configuration user guides, but the BSCANE2 component and JTAG user register access is not described in the 7 series configuration guide.  Any reason this has changed?

Re: BSCANE2 documentation?

Hi,

You are correct, the ports of the BSCANE2 component are listed in the 7 series library guide. What's missing is information on how to use it. The 6 series documentation has a little bit of information, but the 7 series configuration guide no longer even mentions the USER1/2/3/4 registers.

Re: BSCANE2 documentation?

Hi,

 

On 7-Series FPGA, there are up to four BSCANE2 instance for each device, and each of them will handle one JTAG USER instruction (USER1 through USER4) as set with the JTAG_CHAIN attribute. If you need to handle all four USER instructions, instantiate four of the elements and set the JTAG_CHAIN attribute appropriately.

 

port desciption is available in the same user guide which I have already mentioned.

 

thanks
