virtex6 speed grade

Hi,

My name is P Dasarath.

 

I have working on a project with following fpga board configuration.

 

VIRTEX6 XC6VLX240T FF1156 with Speed grade  -1 ( ML605 evalution board).

 

for Gen1 and Gen2 of SATA used the above configuration. It s working fine.

 

For Gen3 the above board is not supporting, so i moved to VIRTEX6 XC6VLX240T FF1156 with Speed grade  -3.

 

Every thing is same except the SPEED GRADE.

 

My question is Can i use the same pin locations for both configuration ( speed grade -1 and -3).

 

I mean  does the both boards ( speed grade -1 and -3 ) have the same pin structure ?

 

Kindly respond as soon as possible.

 

Thanking you,

 

Regards

P Dasarath.

Re: virtex6 speed grade

p,

 

Did you syntehsize, place and route the design with new constraints to match the need for the higher speed?

Re: virtex6 speed grade

pin locations does not depend on speed grade.

Re: virtex6 speed grade

Hello,

 

Speed Grade (-1, -2, -3 ,...) influences a variety of "Timing parameters" in the FPGAs. In modern Xilinx FPGA products, the higher numbers are faster. When you switch to a faster speed grade, it will affect ONLY the timing parameters and it is independent of pin locations... 

 

Regards,
