The synthesis netlist is input to the placement process. The place and route process places each macro from the synthesis netlist into an available location on the target silicon and connects the macros using routing resources available on the target silicon. The placement process analyzes all of the macros used in the design and their connectivity to try to determine an optimal placement for the macros. The placement algorithms take into account a number of technology-specific factors of the target technology to determine whether a particular placement is good or not. After a trial placement and signal route is attempted, the design is analyzed with respect to timing constraints. If the timing constraints are not met, the place and route software continues to try different placements and signal routing to try to meet the constraints.
Typical target devices have areas of the chip where logical functions are placed, and areas where interconnect signals are routed to connect the logical functions. The device is split into a number of logic areas with routing channels that surround the logic areas. Logic areas contain the logical gates to implement the Boolean function of the design. Routing channels contain the signals that are used to connect the logical gates together. For FPGA devices, the routing channels contain programmable interconnect wires. FPGA devices use an onboard RAM to store the value of programmable switches that are used to form the signal interconnections. By enabling the proper sets of pass transistor gates, signal interconnections between logic gates can be formed

What has the author Klaus Melakari written?
Klaus Melakari has written: 'A VHDL simulator in a co-verification environment'
What is meant by an architecture in VHDL programming?
While implementing a system in VHDL, we consider two major aspects. One is the external view of the system and the other is the internal view. To represent these two, we have entity and architecture in VHDL programming. Hence, architecture in VHDL provides the internal structure (or functioning or logic) of the system to be designed.
What is VHDL calculators?
A virtual calculator can be implemented using VHDL. We call it VHDL calculator.
What is meant by 'verification of data'?
It is the checking of data input to a system to ensure that it is what is meant to have been input.
What are the supporting functions by vhdl?
VHDL provides conversion functions and resolution functions.
Is VHDL text or graphic programmed?
VHDL is a text based programming language.
What is the vhdl code for binary to hex convertion?
vhdl code for binary to Hexadecimal ?
Vhdl code for assending order of numbers?
vhdl code for ascending order of numbers
Which operator cannot be synthesized by a VHDL synthesis tool?
"&" operator is not synthesized by VHDL synthesis tool.
Why function in VHDL?
A function is a subprogram written in VHDL. This program can be called and used in other programs.
How do you build 8085 using vhdl?
VHDL is a hardware description language. It describes the functionality of a hardware as a program. If we know the architecture of 8085, the same can be implemented or coded using VHDL.
What is the latest VHDL version?
In 2008, Accellera released VHDL 4.0 to the IEEE for balloting for inclusion in IEEE 1076-2008. The VHDL standard IEEE 1076-2008 was published in January 2009. Currently, IEEE 1076-2008 is the latest version of VHDL.
