+ add sky130_ef_sc_hd__decap_12 decaps in the rtl of gpio_signal_buffering
+ add sky130_ef_sc_hd__decap_12 stub file for openlane; there is no
yosys-parseable verilog model for sky130_ef_sc_hd__decap_12
~ change config of gpio_signal_buffering* to add sky130_ef_sc_hd__decap_12
~ regenerate the gl netlist based on the above changes
gpio_signal_buffering_alt cell (caravan chip). This was
previously done for gpio_signal_buffering (caravel chip) but
the same thing had not previously been done for caravan.
* update caravel with tying `porb_h_in` with `por_l_in` at the `mgmt_core_wrapper` in the top-level layout:
- `porb_h_in` shouldn't be left floating as it is an input to `clkbuf_16`
* add caravel-eco.gds (same as caravel.gds)
* Fixed caravan top level power routing and updated views for mag, gds and lef
* caravan(rtl): updates
~ typos fix
- remove unused pin in chip_io_alt
+ add caravan_power_routing verilog
* Apply automatic changes to Manifest and README.rst
* ~ update caravan openlane configs to add extra cell references
~ correct placment and cell names of some macro in caravan interactive script
* reharden: caravan
+ add non functional blocks
+ add an initial iteration of caravan
* Apply automatic changes to Manifest and README.rst
* Revert "Fixed caravan top level power routing and updated views for mag, gds and lef"
This reverts commit 70628f748a.
* fixed caravan top level power routing

based on new power routing
~ guard rtl chip_io power pins in the power macro guard
* Apply automatic changes to Manifest and README.rst
* fixed caravan top level power routing
* rehadren: caravan
+ add caravan signal routing to openlane run
~ change rtl to guard power and analog against routing by
openlane by ifndef TOP_ROUTING
~ add pr bounadry for caravan signal routing to fix origin issues
* Apply automatic changes to Manifest and README.rst

* This fixes errors in the top level RTL of caravan that failed to
hook up the buffers through the SoC correctly.
* Apply automatic changes to Manifest and README.rst
* reharden: caravan
~ rtl updated
* fixed caravan mag top level
* updated views for caravan + signoff
* fixed top level cell name
* fix syntax error related to signal initialization place in caravan (#319)
* fix syntax error related to signal initialization place in caravan- fixed in caravel in another commit
* Apply automatic changes to Manifest and README.rst

* added views for each step of generating final caravel.gds
* generated the right caravel and caravel-eco gds
* renamed caravel_signoff and removed caravel-non-eco
Co-authored-by: Marwan Abbas <marwan@ciic.c.catx-ext-efabless.internal>
* reharden: caravel
~ shift caravel_clocking due to change in size
~ change the pr boundary of caravel_power_routing mag file
~ regenarate lef of caravel_power_routing
* update pdn for `caravel_clocking` & `digital_pll`
* added script to update and generate the power routing views
* ~ run update_power_routing_views from the caravel root with prboundary
* fix output message
* added power routing lef, mag and gds
* fix update_power_routing_views saving wrong cell name
* reharden: caravel
~ incorperate pdn changes

~ increase width for more spread decaps
+ add or cells to cell exclude
~ change placement density in accordance to area
~ change padding to allow for space for decaps
~ increase height for more spread decap insertion
+ add or cells to cell exclude
~ adjust pdn to have an offset half to pitch
~ change placement density in accordance to area
~ change padding to allow for space for decap insertion
~ enable synth buffering to fix fanout
~ add *buf_1* to no synth list
~ add attribute (* keep *) to the oscillator as dont
touch for yosys
!need to verify that the oscillator remains untouched
the RTL, but cleaned up for macro definitions; this can be used
for LVS. The decap cells were hand-edited in because there is
no way to devine them from the RTL source.
+ add custom interactive script to insert a buffer on user_clk output
and have a large buffer on core_clk
~ change pdn config to match top level
~ change sdc
~ change openlane configuration
