+* Simple POR circuit for Caravel
+*-------------------------------------------------------------------
+*
+* Architecture:
+*
+* Resistive divider sets mvnfet transistor gate voltage to ??V
+* mvnfet current is 240nA nominal
+* mvnfet drives current mirror at 1/400x to 600pA through mvpfet
+* current feeds 1.84pF capacitor (double MiM at 30um x 30um)
+* voltage across capacitor is input to chain of two schmitt trigger
+* inverters.
+*
+* Q = C * V = I * dt
+*
+* t = C * V / I = 1.84pF * 3.3V / 600pA = 10ms
+*
+* ~400x step-down done by mirroring 1:8, 1:7, 1:7 (= 392)
+*
+* From DC sweep test result, V = 0.7575 on the transtor gate at vin
+* Resistor divider at fraction 0.23.
+* This yields resistor lengths of 500 on top, 149 on the bottom
+*
+* Actual response of this circuit by ngspice simulation is 15ms.

+The qflow directory entries are only used to verify the all-digital frequency
+locked loop circuit by running the verilog modules ring_osc2x13 and
+digital_pll_controller seperately through synthesis.
+
+The ring_osc2x13 module is all gate-level except for a small amount of trivial
+glue logic, so the fact that it is synthesized in qflow instead of openlane
+(with a different setup passed to yosys) does not change the core part of the
+ring oscillator that needs to be simulated. The synthesis results in a SPICE
+netlist that can be simulated.
+
+For the digital_pll_controller, it is only needed to have a functional xspice
+circuit of the digital part that can be used in the ngspice simulation.
+
+See the caravel/ngspice/digital_pll directory for the ngspice simulations.
+
+None of the files in this tree are used for the actual synthesis, placement,
+and routing. The source files for qflow are pointers back to the verilog
+module files in caravel/verilog/rtl/ directory.
+
+Qflow was only run through the "synthesis" stage to obtain the necessary
+netlists. These can be recreated on demand from qflow, so the required
+netlists were copied back to caravel/ngspice/digital_pll and the qflow
+directory cleaned out.
+
+To reproduce the results, it is necessary to have the "tech" directory as a
+symbolic link pointing to the open_pdks installation of sky130A.
