Variable

Kathryn provides 3 variable type classes as followed:

1. Module variable

• mMod(#name, #moduleType, varArgs....)
  mMod(x, ExModule, 1)
  //^----------------- example
• this is command to build a module or submodule (depend on where it take) with
  • #name = x variable of module
  • #module = ExModule (as describe in module section)
  • #varArgs = 1 is an argument to put to module

2. Logic variable

• Type	decaration	blockedAsm	nonBlockedAsm
  Register	mReg(#name, #size)	yes	yes
  Wire	mWire(#name, #size)	no	yes
  Value	mVal(#name, #size, #value)	no	no
  Nest	g(#signalName ....)	dep on sigType	dep on sigType
  MemBlock	mMem(#name, #row, #column)	yes	yes

• to slice the Logic variable operand (except memblock) using (#start, #stop) ex. mReg(myVar, 8); myVar(5, 8)

• to index your memory block using [index] ex. mMem(myMem, 256, 8); myMem[10] or myMem[myVar] (if you use dynamic indexing you must ensure that size of indexer is equal to ceiling(log2(depth)))

• for all logic variable assignment whether blockAsm(<=) or nonBlockAsm(=) will be considered as CYCLE CONSIDERED ELEMENT <<<CCE>>> which we will discuss in hybrid design flow section.

3. traditional C++ variable

• all traditional C++ will be Not considered as CCE, it is only used to generate the Hardware design
