Dress Specifications:  Color: White  Fabric: Lace  Length: Long Different designer - Different dress ! Motivation:

Background Different teams use the register HSID But each team creates their own registers code… WHY?!?

Automatically generates registers according to the required specification. The Solution – a Register Management Tool Creates unity in the registers VHD files Enables REUSE Saves money and resources

Manages the registers through the entire project Creates documentation for the components created Leads to an organized – HSID The Solution – a Register Management Tool Alarms in case of incorrect input

Project Specifications 1. Writing a GUI interface through which the user will determine a variety of attributes. GUI demo

COR register simulation WB slave addr = 0010 COR addr = 1110 W/R Encoder Reg_chosen 4 WB Master Functional Block adr_i = 0010 we_i =‘0’ “ ” “ ”

COR register waveform 0 Scenario: the block updates the data while the master reads rd_en =‘1’ Data from block = 1

COR register waveform Results: 0 dout = “1” Dout_valid = ‘1’ updated data is transferred to the WB master reg_data is cleared

COR register waveform 0 Reg_data = “ ” Results: updated data is transferred to the WB master reg_data is cleared

W/R register simulation WB slave addr = 0010 COR addr = 1110 W/R Encoder Reg_chosen 4 WB Master Functional Block “ ” adr_i = 1110 we_i =‘1’ dat_i = “ ” “ ”

W/R register waveform Scenario: WB master writes to register din = 7 and then 8 wr_en = ‘1’ for 2 cycles

W/R register waveform dout = 7 and then 8 din_ack = ‘1’ for 2 cycles Results: updated data from WB master is transferred to register din_ack rises, indicating dout is updated Register not influenced by data from block (reg_in_b)

W/R register waveform Scenario: WB master tries to read from this register’s address (register address is 10) Result: dout_valid rises to ‘1’ Dout_valid = ‘1’ rd_en = ‘1’ addr = 10

W/R register waveform Scenario: WB master tries to read from another register’s address (register address is 10) Result: dout_valid is ‘0’ Dout_valid = ‘0’ rd_en = ‘1’ addr = 15

Project Steps 1.Determine the implementation platform of the user interface and data processing: Excel/MATLAB/C++/C#/JAVA. 2. Full characterization of the tool capabilities. 3. Learning the working environment (Wishbone protocol, advanced VHDL coding, MODELSIM simulation environment). 4.VHDL generic design and simulation. 5.Implementing the GUI and automatic VHDL generation. 6. Final MODELSIM and MATLAB Simulations. In process
