Tim Edwards 024801ab56 Extended the gen_gpio_defaults.py script to handle modifying the 
verilog gate-level netlists to match the correct GPIO default
value assignments, and modify the top level gate-level caravel.v
and caravan.v netlists to match.

Tim Edwards 4cf7aa2983 Changed the synchronized reset to occur on the clock falling edge 
to give more timing margin when reset is released (note to self:
shouldn't the ext_reset also be synchronized?).

Tim Edwards 6482c1e011 Corrected the set_user_id.py script to (1) reverse the position of 
characters in the user_id_textblock layout, which was backwards,
and (2) add a path reference to "hexdigits" for each new character
layout encountered in the file, so that the text block layouts
are found even if "addpath hexdigits" has not been specified.
There were some other corrections to handling gzipped files that
probably does not apply in practice, where "make uncompress" has
been run prior to the set_user_id.py script.

Tim Edwards 0f90c813ed Added a missing route that was not completed in the previous layout 
update.  Also changed the defaults block types in the layout so that
they match the gate-level netlist.  This does not change the behavior
after assembly but lets LVS run correctly on the layout prior to final
assembly.

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.
 2021-11-30 12:31:07 -05:00
Tim Edwards 1035e8b469 Updated caravel and caravan layouts to reflect the simple change 
to housekeeping and the management core wrapper to separate the
wb_cyc_i signal and connect to new signal hk_cyc_o on the
management core.  Also:  Fixed a dangling input (user_clock) on
the housekeeping (minor error caused by the earlier refactoring
and unnoticed because there is no testbench covering that
function).

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.
 2021-11-29 20:17:11 -05:00
Tim Edwards 84c97b74b2 Corrected the instance names in the layout so that they once again 
correspond to what the script gen_gpio_defaults.py is looking for.

Tim Edwards cd4a052344 Made the same change to caravan as was made to caravel in the 
last commit.

Tim Edwards 4dac106297 This (late and invasive) change modifies the housekeeping block to 
add a separate signal for the houskeeping wb_cyc_i wishbone signal,
instead of combining it with the user project's wb_cyc_i.  This
change makes it compatible with the LiteX implementation of the
wishbone bus.

Tim Edwards e2ee74c591 Changed "simple_por" in both caravel and caravan to be an abstract 
view pointing to the contents of ../gds/ so that when the assembled
chip's GDS is generated with "cif *hier write disable", the POR
will continue to have the GDS with the proper hierarchical processing.

Tim Edwards f67f7b6daf Corrected bad paths on two layouts in mag/ and most of the layouts 
in maglef/, all of which were erroneously pointing to paths in
either OpenLane or the user's home directory path.
