PhysDesignRules:812

Jump to solution

Hi ,

 

I am getting the following warning during the bit file generation .

 

What does this warning mean ?. How do I correct it ?. The location this warning is refering to is inside a xilinx IP core.

 

 

WARNING:PhysDesignRules:812 - Dangling pin <DOA1> on
   block:<TX_BURST_ENCODER_INST/TX_TURBO_INTERLEAVED_BITS_SPRAM_INSTANTION/U0/xs
   t_blk_mem_generator/gnativebmg.native_blk_mem_gen/valid.cstr/ramloop[0].ram.r
   /s3_noinit.ram/dpram.dp2x2.ram.A>:<RAMB16_RAMB16A>.

 

With regards

Hi,

 

Looks like you were using Block memory generator core. 

 

If this is true you can safely ignore the warnings.

 

It could be that the tool is implementing the RAM using one or more BRAM16/32 and there are few unconnected input pins of BRAMs (this actually depends on the size of RAM you are implementing). Hence the warning is correct as it complains about dangling pins. But you can safely ignore them as they do not affect the functionality.

 

Regards,

Deepika. 

Thanks,
Deepika.
