Yes, this is the target I am working on. I like to check in more stuff soon :-)10mA wont drive sdmmc full speed, or other hi speed 125mhz interfaces
You are right. We currently working on our Test Wafer - this becomes our first free silicon at all. If you like to play with the Magic Tool, you can already check some test structures here: https://github.com/chipforge/PearlRiver inside the directories of Library/magic and Layout/magic.
Feedback welcome!
We have to characterize all stuff on silicon like resistance / capacitance on different layers first, than put the values back to the Spice model before we can calculate accurate transistor parameters for cells and pads.
Your wish with multiplexed IO cells is still on the to-do-list. And the roughly calculated 10mA driving output cell is for impressing / attracting more people. They like blinking LEDs ;-) - et voilà we do so with on output on the test chip.
