which software are use to design dc to dc boost converter in ultra low voltage Thermoelectric Energy Harvesting. how to take Photograph of die circuit/Chip micrograph.
Jeetendra,
I'm not convinced that software is essential.
Sound understanding of boost converter topology seems to be a fair starting point:
Carlson et al. A 20 mV Input Boost Converter With Efficient Digital Control for Thermoelectric Energy Harvesting, IEEE Journal of Solid-State Circuits ( Volume: 45, Issue: 4, April 2010 )
etc.

etc.
Jeetendra, you could try this also

Input has to be more than 330mV to get any output, you might use two or three TEC in series.
If you dont care for building this and want to simulate only then there are tools from TI.COM

i'm not sure if you actually want to design your own die (e.g. using Cadence packages) or if you just want to utilise one for your application. If it is the latter...
As Thirumurugan suggests, the BQ25505 is an excellent boost converter for low-voltage inputs. In fact after the storage element reaches 1.8 V the input voltage can drop back down to around 100 mV.
Also check the LTC3108 from Linear (now Analog Devices), which allows an input of just 20 mV:
