  • ARM Blog Tells Story of a 20nm Cortex-M0 Test Chip

    All 20nm test chips are learning experiences, and a recent tapeout of a 20nm Cortex-M0 test chip by ARM engineers was no exception. Completed in June 2012, the test chip design used a Cadence digital implementation flow. The story of the test chip is told in a new guest partner blog (I'm the "guest"...

  • Designer View – Low-Power IC Design Challenges and Solutions

    The IC physical design team at Marvell Technology Group Ltd. has a tough challenge. They're under a lot of pressure to minimize power consumption as much as possible, while getting products out the door quickly. In a recorded presentation at the Cadence web site, Murali Natarajan, senior physical...

  • Tips for Fixing Timing Violations and Adopting Best Practices for Optimization with RTL Compiler

    Best Practices for Optimization What should be my considerations while preparing data? Libraries, HDL, Constraints... A good result from a synthesis tool depends greatly on the input data. An old saying "garbage in garbage out" is also true for RTL Compiler. Before attempting to run synthesis...

  • Propagate a clock from .LIB of a block

    Hello all, I am trying to synthesize a module which has a .LIB for one of the blocks. The block has internal clock generators and requires to create a clock on one of the block's ports. I can create the clocks in the top-level by providing hierarchical path. However, I am not able to see the generated...

  • Synthesizing 'x'

    Hi, look at the following code: always @(*) begin o = 2'bxx; if (a) o = 2'd0; else if (b) o = 2'd1; else if (c) o = 2'd2; else if (d) o = 2'd3; end signal o is DC (don't care) if none of the inputs (a,b,c,d) is asserted. I used the 2'bxx value because (1) it's easier to...

  • 8 Users Compare RTL Compiler (RC) vs. Design Compiler (DC) on DeepChip.com

    It was refreshing to see what happened when John Cooley made his latest request for reader feedback on his popular DeepChip website catering to the semiconductor design community. A request had come in from a previous DeepChip post prior to the Design Automation Conference (DAC) as follows: Are there...

  • The Science of Synthesis

    I am passionate about synthesis. Almost 20 years ago I began using Synopsys "Logic Compiler" to do combinational synthesis and optimization from Verilog RTL. At that time it did not support sequential constructs so Flip-Flops had to be manually instantiated in the netlist. Synthesis has matured...
