Device model generator

[ombhilare999]

Previous PE layout (PinCell added only at the PE input-output interface):

New PE layout (PinCell added to every FunCell interface i.e for every constat, ALU, IO pin interface is available):

Changelist for the device model:

• Naming convention added in the dot file for the additional information about the cell. [For more information please look into riken_8_8.dot given in the scripts directory]

  
  Cells inside a PE:
  pe_w32.c.w32.c0.r0.crossbar_mux_0
  pe_w32.c.w32.c0.r0.crossbar_mux_1
  pe_w32.c.w32.c0.r0.crossbar_mux_2
  pe_w32.c.w32.c0.r0.crossbar_mux_3
  pe_w32.c.w32.c0.r0.crossbar_mux_4
  pe_w32.c.w32.c0.r0.crossbar_mux_5
  pe_w32.c.w32.c0.r0.crossbar_mux_6
  pe_w32.c.w32.c0.r0.crossbar_mux_7
  pe_w32.c.w32.c0.r0.crossbar_mux_8
  pe_w32.c.w32.c0.r0.crossbar_mux_9
  pe_w32.c.w32.c0.r0.mux_a
  pe_w32.c.w32.c0.r0.mux_b
  pe_w32.c.w32.c0.r0.const
  pe_w32.c.w32.c0.r0.const.pinA
  pe_w32.c.w32.c0.r0.alu
  pe_w32.c.w32.c0.r0.alu.pinA
  pe_w32.c.w32.c0.r0.alu.pinB
  pe_w32.c.w32.c0.r0.alu.pinO

LS Cells: LS_0 LS_0.inPinA LS_1 LS_1.inPinA

- Due to additional pins the sequence of the elements in the PE is changed to this:

- Overall, when no pins incorporated, the sequence of the cells inside dot graph file earlier was `LS0 --> LS1 --> PE 1 --> PE 2`
- The sequence of the cells inside dot graph file right now `LS0 (LS0, LS0.pinA) --> LS1 (LS1, LS1.pinA) --> PE 1 --> PE 2`
- LS block has bidirectional pin so that it can handle both the load and store operations.
