 # Prerequisites - Design
 
 for logic bist to work properly, design should met these crieria.
 
-1. **Clock Doman**
-    Single domain. All the Sub block should be synchronous and use single clock
+1. **Clock Doman:**
+    All the Sub block should be synchronous and use single clock
 
-2. **Reset**
+2. **Reset:**
     Scan Reset Bypass logic need to implemented 
 
-3. **SRAM**
+3. **SRAM:**
     SRAM input towards digital logic should have scan bypass
 
-4. **Register**
+4. **Register:**
     All the Register should be able to re-initialize with reset, even the two dimensional FIFO.
 
-5. **Input**
+5. **Input:**
     All the Input should be in known state, else add scan bypass logic
