Tim Edwards	1d359690ac	Added testbench for checking that the housekeeping SPI is accessible when ... the user area is powered down. Because this requires some changes to the padframe definition, this testbench currently fails.	2021-11-02 21:58:47 -04:00
Tim Edwards	dd66d1e5ca	Renamed the poorly and awkwardly named "sky130_fd_sc_hvl__lsbufhv2lv_1_wrapped" ... cell to the simpler (and easier to remember) "xres_buf".	2021-10-31 21:43:09 -04:00
Tim Edwards	bc9944ce20	Updated the caravan netlist and implemented the caravan testbench.	2021-10-25 15:08:13 -04:00
Tim Edwards	e5c90daddd	Implemented a system for setting the GPIO power-on defaults through ... via programming. The values for each of the GPIOs at power-up are defined in the "user_defines.v" file. For the verilog, they are applied as parameters. For the layout, they will need to be separately defined cells for each of the GPIOs, or at least for each set of unique default values.	2021-10-23 17:18:30 -04:00
Tim Edwards	332f9ec2e7	Seeding with documentation of pinout and verilog RTL (mostly unchanged ... from original except to remove blocks that are not supposed to be in this repository like the processor core and the storage).	2021-10-12 16:31:42 -04:00
