LogiCORE RAM-Base Shift Register - Why is the LogiCORE RAM-Based Shift Register v9.0 almost 10 times larger than the LogiCORE RAM-Based Shift Register v8.0, when targeting Virtex or Spartan-II?

Description

Why is the LogiCORE RAM-Based Shift Register v9.0 almost 10 times larger than the LogiCORE RAM-Based Shift Register v8.0, when targeting Virtex or Spartan-II?

Solution

This is due to a bug in the implementation tools used to generate the RAM-Based Shift Register v9.0. 

 

To work around this problem, use LogiCORE RAM-Based Shift Register v8.0.
