18 rounds encryption in embedded? I have a power trace of a decryption.
It seems like I'm watching a 18 rounds decryption algorithm.
I cannot think about any other algorithm implemented in ASIC except Cammelia who has 18 rounds.

Which other algorithms are commonly used in ASIC and has 18 rounds ?

Also it seems it receive 128 bits block size.
The only 2 "common" algorithms that I know off the top of my head with 18 rounds are Clefia and Camellia with 128-bit keys.

Anubis may also be an option, I believe that with a 320-bit key it uses 18 rounds, I have no idea why that would be used instead of AES.

I suppose it is also trivial to add rounds to AES or Twofish in hardware, both the key schedule and round function support additional rounds without modification to their core.
