This project includes the RTL Design, Validation, and Implementation of an Elevator Controller. it supports any arbirataty number of floors and can specified with the generic N parameter with each floor containing up and down buttons
It contains 2 main parts the Control Unit and the Resolver.
| Generic name | Type | Value |
|---|---|---|
| N | integer | 10 |
| clk_freq | integer | 50_000_000 |
| Port name | Direction | Type |
|---|---|---|
| clk | in | std_logic |
| reset_n | in | std_logic |
| req_i | in | std_logic_vector(integer(ceil(log2(real(N)))) downto 0) |
| mv_up | out | std_logic |
| mv_down | out | std_logic |
| door_open | out | std_logic |
| floor | out | std_logic_vector(integer(ceil(log2(real(N)))) - 1 downto 0) |
- U1: one_sec_timer
- floor_counter_inst: component floor_counter
it takes all the buttons and outputs only one single request to the control unit
