Dennis	e05408e8a1	Add support for inline-comments ... It is possible to enable them for: - fields - registers - regfiles - addrmaps	2021-10-17 00:53:22 -07:00
Dennis	16d1774cd2	Remove log.py TODO that got already implemented	2021-10-14 23:29:19 -07:00
Dennis	b23ddded74	Package with enums shall not be dumped if no enums are present	2021-10-14 23:22:01 -07:00
Dennis	6e355c62af	Add support for rsvdset and rsvdsetX	2021-10-14 23:16:30 -07:00
Dennis	4ba047dd2a	Extend test_simple_rw_reg with 3 more tests ... The following tests are now included: - Check access to registers over AHB bus - Check access to register over HW interface - Check access to register over HW interface if hw_wr-input is disabled. - Check if the slave responds with a correct error sequence if an illegal address is accessed.	2021-10-11 23:49:31 -07:00
Dennis	ed08d4bd35	Fix external-register bug where the sw_rd-wire is missing ... This was introduced in dc37c879 because sw_rd-wires got removed here for registers that don't need it.	2021-10-06 23:39:04 -07:00
Dennis	57d8050d56	Fix bug in bus-width of amba3ahblite-widget's instantiation	2021-10-06 23:28:48 -07:00
Dennis	ace4238ccf	Fix bug in external read-interface ... In dc37c879, some properties got saved in self.properties of a Component. In that commit, self.properties['sw_rd'] never got set. For that reason, external registers with a read-interface were broken.	2021-10-06 23:20:55 -07:00
Dennis	aa770073c4	Ensure that file-log gets dumped in --out_dir	2021-10-03 23:31:22 -07:00
Dennis	7d5ddaf47c	Add first simple test with a simple 2-dimensional array	2021-10-03 23:24:16 -07:00
Dennis	c4dca87ab5	Ensure that HSIZE is flopped and that data is shifted according to HADDR/HSIZE	2021-10-03 23:22:54 -07:00
Dennis	aada5c5853	Prepare Makefiles for regression flow with CocoTB tests	2021-10-03 18:07:48 -07:00
Dennis	694f7c124e	Make stickybit available for non-intr fields and add support for sticky	2021-10-03 15:48:27 -07:00
Dennis	f30dce67c2	Give all genvars an gv_ prefix to prevent collisions	2021-10-02 00:38:31 -07:00
Dennis	dc37c87944	Ensure that sw_rd/sw_wr wires are only generated if they are required	2021-10-02 00:32:04 -07:00
Dennis	8756945a6d	Repair multi-enumerations in one regfile bug ... When a regfile did use enumerations from multiple scopes this messed up the eventual packages because every regfile only assumed 1 scope. This is fixed now. TODO: Check what happens if enums are defined in the register scope.	2021-09-30 00:11:50 -07:00
Dennis	d3bfdeb3f0	Buswidth is now variable, based on widest register ... Fixes #2.	2021-09-26 21:16:49 -07:00
Dennis	6359883c27	Finish initial version of interrupt suport, closes #1 ... The software is now able to create most interrupt combinations of Section 9.9 of the SystemRDL 2.0 LRM. It supports stickybit/non-stickybit interrupts, it support posedge, negedge, bothedge, and level interrupts, and it is able to generate all surrounding logic. This commit also fixes a reset-bug that caused registers that were reset to 0 to be not reset (because 'if not reset_value' will return True if the 'reset_value' is 0).	2021-09-26 19:40:04 -07:00
Dennis	c52e59abd0	Add basic interrupt framework ... Up to this point, interrupt outputs are generated and intr, enable, mask, haltenable, and haltmask are supported. stick, stikcybit and the different types of interrupts are not yet supported. This commit also removes the option to turn off santiy checking. This is a bad idea anyway...	2021-09-25 20:49:39 -07:00
Dennis	8ea1ad97da	Fix AMBA AHB 3 Lite widget so that first register transactions succeed	2021-09-25 13:01:23 -07:00
Dennis	28edf17a1c	Pull assignment of multiplexer wires into generate for-loop	2021-09-19 23:24:59 -07:00
Dennis	887164dd52	Flip r_vld and w_vld in <REG>_sw_wr/<REG>_sw_rd assignment	2021-09-15 23:47:36 -07:00
Dennis	fea0019aa8	Replace old 'reg_clk' name by more generic 'clk' ... The reason is that the template will always assume that the bus signals and the registers are synchronous. Designers should implement possible synchronization logic outside of this block.	2021-09-15 23:42:52 -07:00
Dennis	61cd1fbfe3	Add directory that will contain SystemRDL files for tests	2021-09-13 22:09:04 -07:00
Dennis	85aa2f903c	Flops must not update when HREADYOUT == 0, not when r2b.rdy == 0	2021-09-13 21:52:35 -07:00
Dennis	a27b57009b	Fix two issues to get AMBA widget compile clean under Verilator ... The former issue was a Lint warning. HADDR % HSIZE is a modulo operation of a 32-bit and 3-bit variable. It is cleaner to only use the LSB of HADDR. Furthermore, Verilator does not support unpacked arrays in packages.	2021-09-12 19:44:42 -07:00
Dennis	240fba8e12	Resolve bug for addrmaps without any genvars ... In this case, there would be a line with `genvars ;`. This is not compilable by SystemVerilog compilers.	2021-09-12 19:44:42 -07:00
Dennis	17f1877390	Add very basic, incomplete statemachine for AHB protocol	2021-09-12 17:13:44 -07:00
Dennis	6142a13653	Add genvar-key to write-signals of external registers	2021-09-12 17:09:33 -07:00
Dennis	b89bf3663f	Fix issue with read-mux assignment for multidimensional registers	2021-09-12 16:44:37 -07:00
Dennis	5475bbf62d	Fix issue that causes 'input None' if no reset is present for a field	2021-09-06 22:42:32 -07:00
Dennis	24d5534037	Add support for external registers ... Every single field and every single alias (!) has its own interface to the surrounding hardware. This is required to give users the maximum amount of freedom when defining certain properties in RDL.	2021-09-06 18:48:37 -07:00
Dennis	a3b6e1caf8	Add file-exist check for input file	2021-09-06 11:58:01 -07:00
Dennis	4f2ac8868a	Rename regs.yaml to register.yaml for consistency reasons	2021-09-06 00:29:29 -07:00
Dennis	c689190080	Add proper support for rdy & error indication in read multiplexer ... The error indication is generated if: - A non-existent register gets read - An existent register gets read but not a single bit can be succesfully read or written. As soon as 1 bit succeeds don't return an error.	2021-09-06 00:26:08 -07:00
Dennis	2f38d30d76	Fix assignment to _rd_mux_in for arrays	2021-08-22 21:50:58 -07:00
Dennis	08b7de9544	Fix read-multiplexer bug in case a reg is _not_ an array	2021-08-22 21:43:53 -07:00
Dennis	d298e79ec1	Fix bug where an empty search path caused srdl2sv to crash	2021-08-22 21:27:44 -07:00
Dennis	8881821252	Give more consistent names to modules and packages	2021-08-22 20:46:35 -07:00
Dennis	5e4a954a0c	Add _very incomplete_ AMBA 3 AHB Lite widget ... This is just a start on the first widget. It is still very limited and not yet functional in any way.	2021-08-22 20:38:56 -07:00
Dennis	145ac70123	Add email address to MIT license	2021-08-15 14:12:21 -07:00
Dennis	78742daba7	Add support for 'next' property to fields	2021-08-15 14:10:22 -07:00
Dennis	a74377bae7	Add underflow property and checker if referenced properties exist	2021-08-15 12:56:41 -07:00
Dennis	1d5bc8b75e	Fix assignment of overflow to increment input of counter	2021-08-15 12:28:07 -07:00
Dennis	fd75e4c84c	Update systemrdl-compiler to v1.19.0 ... The main difference in this release (https://github.com/SystemRDL/systemrdl-compiler/releases/tag/v1.19.0) is that FieldNode.get_property('resetsignal') will now default to finding the nearest in-scope field reset signal if not explicitly set. The same is true for the cpuif-signal. Before this commit, the addmap-class searched for resetsignal and cpuif signals and saved it for the fields to be picked up later. This code is now not required anymore	2021-08-15 11:46:40 -07:00
Dennis	1d50b2b457	Add incrthreshold/decrthreshold support ... It is still not possible to assign overflow/threshold signals to any input of a different register!	2021-06-29 00:14:51 +02:00
Dennis	18204d9a3e	Improve counter property ... The counter now covers more corner cases regarding saturation. Furthermore, a bug that caused incr & decr-counters to always inadvertently increment and decrement, even if only one of the two signals was set. Furthermore, the overflow signal is now generated in RTL. Still missing: - incrthreshold/decrthreshold is not yet supported - It is not yet supported to assign an underflow/overflow to the input of another counter.	2021-06-28 23:58:45 +02:00
Dennis	4144329f3f	Add comment to delineate between counters and multiplexer assignment	2021-06-28 23:57:32 +02:00
Dennis	a0dd59d19a	Add hwenable and hwmask property	2021-06-28 12:48:17 +02:00
