xapp524 12-bit 1-wire mode will not synthezise

Jump to solution

Hi,

I put the code of xapp524 into my Vivado Artix project and discovered following:

* 16-bit 2-wire => implements

* 16-bit 1-wire => implements

* 12-bit 2-wire => implements

* 12-bit 1-wire => error on synthesize

 

The error happens in AdcFrame.vhd.

IntFrmSrdsDatEvn signal is defined as a slv (2 downto 0) signal when width=12-bit.

This signal is fed to DoubleNibbleDetect when wire=1 in Gen_1_FrmBus, and here is the flaw:

DoubleNibbleDetect has a fixed input and output width of (3 downto 0) and IntFrmSrdsDatEvn is (2 downto 0)

 

How to fix?

In the end I got this issue solved by help of my FAE and Marc Defossez.

 

This zip contains settings for 12-bit 4ch LVDS.

I have only used the files included in the zip.

 

When the zip is unpacked, it will overwrite the existing files so pay attention.

 

And we don't guarantee that the resulting logic actually works, so please don't bombard me with request to fix anything, but if you find actual error in the files which will prevent xapp524 to work for evaluation purposes for other users, please report back in *this* thread.

Hi there,

 

On Vivado 2015.4, it also won't synthesize.
