  • 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"...

  • LEC issue - "elaborate" vs. "synthesize -to_generic"

    Hi, When running LEC on golden-(elaborate) and revise-(synthesize -to_generic) getting one NON-EQ compare point. The following RC attributes didn't help: set_attribute prune_unused_logic false [find [find / -inst TOP/SUB ] -ignorecase -pin *] set_attribute prune_unused_logic false [find [find / ...

  • 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...

  • power estimation using rc

    Hi all, I got a question about power estimation using cadence rc. I have two designs in HDL. Both of then have a 1-bit full adder. After synthsis, and post-simulation with the netlist with the same test data, I found the output toggle rate of these two 1-bit full adder are different, even though they...

  • RC area information

    Hi ! I have a very general question concerning the RC : Where does the RC get the area information from after the elaboration process? Is it just estimated without concerning the technology libraries? Thank for your support, Alex'

  • 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...

  • RC: clock gating

    Hello, What is the right way to insert clock gating in RC script? I found the following flag: set_attribute lp_insert_clock_gating true Is it enough or there is something else needed? How should I translate the following instructions from DC for RC: set_clock_gating_style -sequential_cell latch \ -control_point...
