what are the different ways you can represent the exact same design using:

A. VHDL

B. state diagrams

C. sequences

Expert Solution

1. VHDL can define a design in three different ways or sometimes can say in four ways namely:

(i) Behavioral : Defines the design behavior without any regard to internal description of the design

(ii) Data Flow : Relates output of the design with the inputs

(iii) Structural : Top level module builds upon multiple submodules

(iv) Mixed Mode : Combination of the three listed above

2. State Diagram

(i) Mealy State diagram: input and output shown on transition arcs

(ii) Moore State diagram: transition arc just mentions inputs. output is state dependent

Further different encoding techniques of states like binary encoding, one hot state assigment etc. causes variation in number of states

3. Sequences

Based on hardware like type of flip flops to be used , truth table is built considering excitation equation, characteristics and transition equations.

Also sequencing circuits are used to move the actuator in defined sequence.

Design B: Using behavioral VHDL, design a Mealy-type finite state machine that detects input test vector that contains the sequence of ‘10’. If the sequence ‘10’ is detected, the output Z should go high. The input is to be named W, the output is to be named Z, a Clock input is to be used and an active low reset signal (Resetn) should asynchronously reset the machine. a) Draw the Mealy-type state diagram for the FSM. b) Write the VHDL...

Analyst B , following the exact same procedure, carries out an analysis of the same acid and reports a concentration of 6.772 ± 0.004 M, after performing 6 successful titrations (no data was rejected). Questions:Is this result obtained by Analyst B in agreement with that of Analyst A, at a 90% confidence level? The certified analysis record for the concentrated sulfuric acid is found and states that the acid has a concentration of 6.759 M. Do either of the Analysts...
