rtl model

i am a bit confused about RTL models in an HDL
what is it and how does it differ from behavioral and structural models???

thnx

what does rtl mean

Hi

RTL model is nothing but a synthesizable HDL model


You can design a system in different (behavioral, structural, etc.) ways. But it becomes the RTL model only when the written code is synthesizable.

rtl modelling

thnx alot for making me clear on this....

so does this mean that i can have a behavioral model that is considered RTL if it is simple and easily synthesized....???
 

rtl modeling

RTL- A kind of hardware description language (HDL) used in describing the registers of a computer or digital electronic system, and the way in which data is transferred between them. 2. An intermediate code for a machine with an infinite number of registers, used for machine-independent optimisation
 
what does rtl mean?

RTL is a combination of Behavioral n Data flow modelling which shud be synthesizable

ali,
u can say that as a RTL but if its a optimized 1 then u can say its as a good RTL

RTL stands for Register Transfer Language. It is basically used to denote the transfer of information in registers. HDl is language for computer simulation purposes. RTL has no relation to Computer simulation.
 

what is rtl model

If the HDL(dataflow/structural/behavioral/any othercombination) is synthesizable, then the design is implimentable in hardware. So that the synthesizable HDL(dataflow/structural/behavioral/any othercombination) is called RTL model.
 

rtl means

If something that is synthsizable is called RTL, then what about languages like HandelC and others that claims beeing high level synthesizable languages? Are they RTL? Are they hidgh level?
 

what does rrtl mean?

VHDL, Verilog HDL, HandelC, etc. These are all high level languages. A high level language program, which is sinthesizable is called an RTL model. If the high level language program is not sinthesizable, then we can't impliment the design in hardware, so that it can not be an RTL model.
 

what is a rtl model

RTL description is more complex and less technology dependent than behavior hardware description.

RTL description is less complex and less technology dependent than transistor level description.

With behavior description you can easy describe complex sistems as memories, ALUs, and etc. For 32-bit adder description you need only simple equation Z=X+Y where X,Y and Z are 32-bit vectors. This kind of description is very easy for simulation.

Simulation of previous example in RTL is more complex and requires more processor time.

Transistor level simulation with HSPICE is very complex and requires powerfull processing unit.
 

what does database modeling mean?

RTL stands for Register Transfer Level. It's a behavioral design concept in which you make HDL models of registered circuits and how signals interact between them such as memories, flip flops, latches, shift registers, and so on. As many people said, they are fully synthesizeable, because they are written using basic HDL structures (not functions or fancy things). The IEEE 1076 recomendation is a good reference to understand the RTL concepts (in VHDL).



And also the IEEE 1364.1 (verilog recommendation for RTL synthesys):
 

what is an rtl model

It means register transfer level ....
 

what does transistor level mean

rtl is register transfer logic.....basically it can be behavoral or data flow but should be synthesizable.......main stress will going for rtl level modeling is how data will flow between various stages of a design separated by registers(flops or latches).......
