RTL PROJECTS -VLSI PROJECT


REGISTER-TRANSFER LEVEL Register-transfer-level abstraction is used in hardware description languages (HDLs) like Verilog and VHDL to create high-level representations of a circuit, from which lower-level representations and ultimately actual wiring can be derived. Design at the RTL level is typical practice in modern digital design.

Power reduction through RTL clock gating
free download
This paper describes a design methodology for reducing ASIC power consumption through use of the RTL clock gating feature in Synopsys Power Compiler. This feature causes inactive clocked elements to have clock gating logic automatically inserted which reduces

Efficient sequential ATPG for functional RTL circuits
free download
We present an efficient register-transfer level automatic test pattern generation (ATPG) algorithm. First, our ATPG generates a series of sequential justification and propagation paths for each RTL primitive via a deterministic branch-and-bound search process, called a

Bridging High-Level Synthesis to RTL Technology Libraries.
free download
The output of high-level synthesis typically consists of a netlist of generic RTL components and a state sequencing table. While module generators and logic synthesis tools can be used to map RTL components into standard cells or layout geometries, they cannot provide

C-based interactive RTL design methodology
free download
Much effort in RTL design has been devoted to developing push-button types of tools. However, given the highly complex nature of RTL design, interactive design space exploration with assistance of tools and algorithms can be more effective. In this report, we

RTL coding styles that yield simulation and synthesis mismatches
free download
This paper details, with examples, Verilog coding styles that will cause a mismatch between preand post-synthesis simulations. Frequently, these mismatches are not discovered until after silicon has been generated, and thus require the design to be re-submitted for a

Optimized RTL design and implementation of LZW algorithm for high bandwidth applications
free download
This paper presents a high-speed low-complexity Register Transfer Logic ( RTL ) design and implementation of the lossless Lempel-Ziv-Welch (LZW) algorithm on Xilinx Virtex II device family for High Bandwidth Applications. Comparative analysis of the proposed design with

Formal verification of floating-point RTL at AMD using the ACL2 theorem prover
free download
We describe a methodology for the formal verification of the correctness, including IEEE- compliance, of register-transfer level models of floating-point hardware designs, and its application to the floating-point units of a series of commercial microprocessors produced by

To answer the second question, semiconductor fabrications can now put millions of logic gates on a single chip using deep sub-micron technology. This rapid increase in the complexity of chips and systems has outstripped traditional verification techniques. This is

Automatic generation of fault tolerant VHDL designs in RTL
free download
Fault Tolerance (FT) is an important issue in electronic devices. Detecting and even correcting internal faults during normal operation makes possible the usage of these circuits in critical applications. FT has been taken into account for many years during design process
