--- Comment #10 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
# create tutorial / workflow page for setup, establish first layout
we need the alliance2/coriolis workflow documented, a suite of tutorials
found (or written), and a "test project" to be done which gives a guide
to completion time of layout.

# layout for single-core 180nm ASIC
do layout for single-core 180nm ASIC including 1st level cache.
also peripherals: minimum priority is SDRAM 32 bit, 16550 UART, JTAG and SPI.
secondary priorities are 64 bit SDRAM, GPIO, PWM, EINT, QSPI, SDMMC, RGBTTL,
I2C and the pinmux.
package is to be QFP, maximum around 200 pins only including power and ground.
