-===== Announcements =====
-[20250323] Welcome to NMK206 info page (for 007 lab sessions only)!
-[20250424] Soft reminder: Lab Assessment 1 @202500420-0800!
-===== Lab Session =====
-I am using [[https://en.wikipedia.org/wiki/Takahashi_method|Takahashi Method]] for these slides (Actually, I broke that method by adding diagrams and long codes because I think my students need them). You will find them hard to understand if you do not attend my sessions. So, that is the 'advantage' I gave to those who actually listen in class 8-)

-==== Verilog Coding Rule ====
-This is the coding rule that I impose on my students. You will be penalized during assessments if it is not adhered to.
-  - One file for one module
-    * **RULE**: 1 file 1 module
-  - **File name must be the same as module name**
-    * **RULE**: file name === module name (.v)
-  - All circuit (module) must have a testbench (tb)
-    * tb is a also module (so, separate file)
-    * **RULE**: All module MUST have a testbench
-    * **RULE**: Tb name === module name + _tb
-  - Use Verilog95 module declaration
-    * Port list contain names only (separate input/output declaration)
-    * Port connection(s) MUST BE specified using ordered list
-    * **RULE**: Port connection(s) by ordered list ONLY!
-  - Modules for combinational logic should only use wire/assign statements
-    * reg/always reserved for sequential logic and testbench modules
-    * **RULE**: comb. logic use assign/wire only!
-  - Only basic logic gates are allowed
-    * Can only use AND/OR/INV in your logic implementation
-    * XOR logic is allowed for **lab project only**
-    * **RULE**: allowed operators AND, OR, INV
-  - Assign statements can only have ONE binary operator
-    * Multiple bitwise inverts (~) are ok (they are unary operators)
-    * **RULE**: 2-input logic gates ONLY
-  - ALL nets (wire/reg) MUST BE declared.
-    * some compiler may allow using without declaration
-    * for my assessments, they MUST BE declared
-    * **RULE**: All signals @wire must be declared!
-==== Lab Code (202425s2) Archive ====
-Complete template for a simple 4-bit processor core (as discussed during class) available {{ :archive:nmk206:nmk206-upcore_20250527.zip |here}}.
-==== Lab Code (202425s2) Extra ====
-Here is an example code to utilize the carry/borrow signals of our add/subtract modules at ALU level. You may use this to create add-with-carry and subtract-with-borrow functions (hint: you need a selector signal to 'enable' the carry/borrow in signals {iC} and {iB}).

-// separate flag bits for borrow and carry
-assign oF = { 2'b00 , oB, oC };
-// should get from same bit position
-assign iB = iF[1];
-assign iC = iF[0];

-==== Lab Project (202425s2) Requirements ====
-This is also shared in Google Doc format (link available in Google Classroom).
-<file text nmk206-202425s2_labproject.txt>
------------
-LAB PROJECT
------------
-You are required to implement a soft-processor core (HDL-based) with the
-following minimum requirements:
-  - 8-bit microprocessor (instruction size, register size, etc.)
-  - 8 general purpose registers
-  - 8 ALU functions
-  - basic instruction set
-    = move data between registers
-    = perform basic ALU operations
-    = load register with immediate value
-These requirements are necessary for submission and minimum grade B.
-More functionality means better grades:
-  - 16-bit/32-bit microprocessor
-  - carry circuit for adder (>8b)
-  - integer multiply/divide circuit (structural code - NOT behavior)
-  - bit-level manipulation (towards microcontroller)
-  - instruction fetch unit and memory interface
-Note#1: Auto-0 for downloaded codes!
-Note#2: This is a group assignment, but marks will be evaluated individually.
-Assessment deliverables:
-) Verilog source files in a single ZIP file
-- make sure only Verilog files are included in the file
-- make sure all modules have each a proper testbench
-- must be self-checking testbenches
-) Technical Document (Specifications)
-- not more than 10 pages, no cover page (only list of members' names)
-- content:
-  = short summary of features
-  = block diagram of design
-  = list of instructions (description and op-code)
-) An online demonstration / Q&A
-- not more than 20 minutes
-- content:
-  = short summary of what has been implemented
-  = if completed, demonstrate running the top-level testbench
-  = if NOT completed, demonstrate running component-level testbenches
-PROJECT DUE: Lab Session@W14/14 (Item 1&2). Item 3 TBD.
-Extra Info:
-- each student may email in a contribution percentage information:
-  = list all group members (specify project contribution percentage of each)
-  = percentage values should total up to 100% (may use fraction e.g. 1/3)
-Note: this is optional,but if a member decides to do this, please advise
-the others in group to do the same
