Re: [Arm-netbook] New Risc-V fully free chip

http://rhombus-tech.net/riscv/shakti/m_class/pinouts/ added the smartphone/tablet scenario, added DDR3, SYS and POWER pins total comes to 290! that's around 18x18 on a side, maybe 19x19 to make space for routing, which in a BGA form-factor @ 0.8mm pitch would be a 15x15mm package! 0.8mm

could i ask people for some help, here? http://rhombus-tech.net/riscv/shakti/m_class/pinouts/ http://rhombus-tech.net/riscv/shakti/m_class/pinouts.py i'm looking for scenarios, to be added to the above, as "tests" of the SoC multiplexing pinouts. it's a mobile-class, 32-bit-wire
