Die Size Calculator

Calculating the die size requires a knowledge of what processes will meet the electrical design specifications and production requirements while staying in budget.

Information used in the calculation include:

  • Estimated production volume
  • Approximate budget
  • Analog blocks required
  • Digital logic required
  • Number of pads needed
  • Device speed

Because of the proprietary nature of some of the calculations, we cannot provide an online calculator. Please contact iSine to get an estimate of your die size in a variety of technologies.

Die Size Calculation Example

Die size is calculated using sizes of known cell libraries, IP blocks, digital gate count, routing area estimates, and new block area estimates by the circuit designer/supplier.

In the pdf example (, a small mixed signal design die size is estimated in three technologies appropriate to the circuit size and product volume. It contains 60K gates of digital logic, plus various analog functions. The design has 24 pads.

Each sub-block is listed along with its area in each technology. Pad area, digital, and analog sections are calculated separately then combined to give the following results:

  • die size
  • die yield per wafer
  • number of wafers needed for production annually
  • amortized NRE cost per die

iSine is your complete resource for ASIC design - from concept to manufacturing and testing. We have expertise in system architecture, VHDL, Verilog, gate arrays, mixed signal, full custom analog, digital, high-voltage and low-power designs.
