 -- Purpose:
---   Pass the sosi data fields or force them to zero. All other sosi fields
---   are passed on unchanged.
+--   Force the sosi data,re,im field to constant or incrementing value in a
+--   block or pass on.
+--
+--   See also dp_force_data_serial.vhd to force data at a specific index in
+--   a block.
 -- Description:
 --   The force_en input dynamically enables or disables the entire force
 --   function.
---   The dp_force_data_parallel affects all valid data in a block, it can set
---   the data to a constant or to an incrmenting series. To affect valid data
---   at a specific index in a block use dp_force_data_serial.
+--
 --   Default the force value is constant, but using the generics it can be 
 --   made to automatically increment for every valid and restart at sync or
 --   sop.
