manarabdelaty aa766f9144 [DATA] Update caravel_clocking module 2021-12-05 19:44:28 +02:00
Tim Edwards bd6af6dddc Modified all of the Makefiles to better handle the GL netlist simulations, 
which is now done through setting an environment variable to point to the
location of the management SoC wrapper.  Added the missing user project
wrappers to the GL directory (copied from the original caravel repository),
and also the GL version of chip_io_alt.  Modified the caravan_netlists and
caravel_netlists files to import the correct list of gate level netlists,
which has been reduced by moving "include" statements for components of the
management SoC into the management SoC repository (e.g., caravel_pico).

manarabdelaty 0067bd5b7c [DATA] Update caravel_clocking/digital_pll/housekeeping 2021-12-02 21:09:43 +02:00
Tim Edwards e0a318d2bf Fixed the GL verilog for caravel and caravan to add the two changes 
just made to the RTL verilog and layout, to separate out hk_cyc_o
and to hook up the housekeeping user_clock input.

manarabdelaty c4efcec989 [DATA] Update housekeeping views 2021-11-30 13:00:33 +02:00
Tim Edwards 4c0a2303b1 Modified the GL netlists to match the layout for the GPIO defaults 
blocks;  that is, there are special versions of the block for the
first 6 GPIO pins.  That should allow the GL netlists to simulate,
although the end goal is to have the gen_gpio_defaults.py script
modify the GL netlists to exactly match the configuration, as is
done for the .mag layouts.

Tim Edwards fe21089505 Updated caravan with the same addition of four spare logic blocks 
as was made to caravel.
 2021-11-24 17:10:05 -05:00
Tim Edwards be98da0fe6 Added spare logic block to caravel layout and verilog GL, wired 
it to the power supply, and checked top-level LVS.

manarabdelaty 83e150bf25 [DATA] Add spare_logic_block 2021-11-24 20:36:23 +02:00
Tim Edwards 5d3f2a26f4 Corrected the Caravel layout and the Caravel and Caravan GL netlists 
to resolve the problem with the typo that caused the propagated
GPIO serial load, reset, and clock signals to get scrambled on the
user2 side.  Caravel is now LVS clean again (Caravan needs layout
work).
 2021-11-23 11:47:17 -05:00
Tim Edwards 08a2c90940 Made updates to correct LVS errors in caravan. Found one major error in the RTL 
verilog for both caravel and caravan.  Hand-edited the RTL and GL netlists to
correct this;  still need to correct the layouts.  The error causes the user1
side clock, load, and reset buffers to drive the user2 side as well as the user1
side, making a huge mess of the routing.  Will route this by hand.

manarabdelaty aeffe4756a [DATA] Add caravan layout 2021-11-22 23:10:25 +02:00
Tim Edwards cd68a2aeff Made several corrections to errors found in the netlists: (1) 
Fixed rstb_h, which was being input to low-voltage blocks.  (2)
Fixed flash_csb_ieb_core and flash_clk_ieb_core, which were not
output from housekeeping as they should be;  the solution was
to tie the INP_DIS lines low at the pad by connecting them to
the TIE_LO_ESD line.  This should probably be addressed in
housekeeping but would change the current pinout.
