Changing Block Parameters During Simulation

Some blocks have parameters which cannot be changed during simulation. In past releases, changes to these parameters were simply ignored. Now, attempts to change these parameters will generate a warning.

FIR Rate Conversion

The FIR Rate conversion block has been re-implemented to improve computational performance. Additionally, it can now handle vectorized inputs.

Buffer and Unbuffer

All Buffer and Unbuffer blocks now handle vectorized inputs. Additionally, the Buffer blocks can now take initial conditions. Similar improvements have been made to the Commutator and Distributor blocks.

Delay

Now supports specification of initial conditions from the block dialog.

Diagonal Matrix

Now supports specification of a non-constant diagonal.

Zero Pad and Complex Zero Pad

Now supports a checkbox to disable truncation of input vector width

Vector Scope Blocks

All vector scope blocks (in DSP Sinks) provide an additional option to record the current scope position into the block dialog.
