For this project, we'll be completing the Octave Shifter, Version 2 block.

In project gj22-12 Octave-Counter Adder, we analyzed a circuit to take the two's complement if the octave counter contained a negative number. This produced a positive number, with the LEFT_RIGHT signal serving as a sign bit.
In project gj26-12 Octave Counter, we added-on the octave counter itself.
In this project, we'll be adding-on the octave shift register itself , along with the Count-and-Stop block we analyzed in project gj16-18.

Here are the directions for this project:

Create a folder called gj15_15_octave_shifter_ver2
Create a new project that will live in the gj15_15 folder.
Right-click here to download the partial schematic shown above, and save it in the folder you just created.
Right-click here to download the test vector file.
Right-click here to download the Count-and-Stop block.
Import the two schematic files into the project.
Import the test vector file.
Compile the Count-and-Stop block.
Generate a symbol for the Count-and-Stop block.
Open the library manager, and tell it you'll be using folder gj15_15_octave_shifter_ver2
At the left of the partial schematic, put in gates like you did in project gj26-12 Octave Counter.
Use the Count-and-Stop block to provide an enable signal to the shift register so that the shift register will shift the number of times specified by OCTCNTR0, OCTCNTR1, OCTCNTR2.
Connect the RL input of the shift register to a signal that will make the shift register shift in the correct direction.
On the right-hand side of the schematic, you shouldn't need anything more than the Count-and-Stop block and an inverter.
