Dennis	5a00d48c34	Add RDL example with compiled hierarchical regfiles	2021-10-28 22:55:28 -07:00
Dennis	738be4ddc4	Update README.md with output-file information	2021-10-27 23:57:15 -07:00
Dennis	e6cfec9c32	Update srdl2sv examples with widget<->interface changes ... These changes were introduced in 85f7808 in order to close #4.	2021-10-27 23:33:42 -07:00
Dennis	85f7808362	Closes #4: Add support for hierarchical addrmaps ... Every time an addrmap is detected within another addrmap, a new context will be opened and a separate RTL file will be created. All addrmaps will have the same bus-wdiget, but it might be possible that different addrmaps have different maximum regwidths. For that reason, it was necessary to change the non-generic srd2sv_if_pkg to a parametrizable interface. Almost all changes to the templates in this commit are due to name changes from 'b2r' and 'r2b' to 'widget_if'.	2021-10-27 23:27:29 -07:00
Dennis	ac693f0c02	Change default logging settings ... STDOUT now will get INFO-level logging by default. The file output will get no logging by default.	2021-10-27 23:22:27 -07:00
Dennis	b8e9adb1f0	Add hierarchical interrupts under examples ... The SystemRDL that was added comes from Section 17.2 "Understanding hierarchical interrupts in SystemRDL" of the SystemRDL 2.0 LRM. The present code succesfully compiles.	2021-10-24 23:33:01 -07:00
Dennis	eb3f1dd57e	Resolve UnboundLocalError bug when SignalNodes are instantiated ... This happened in AddrMap and RegFile because a the width of a new variable 'new_child' is performed. However, SignalNodes will not create such a child.	2021-10-24 23:19:22 -07:00
Dennis	27c5931101	Add option to add no bus-widget ... If this option is defined, there will be a direct interface to the b2r and r2b interface. The structs will be flattened out to wires for legacy reasons. This closes #3.	2021-10-24 22:09:16 -07:00
Dennis	0ab368113e	Move MIT LICENSE to templates & widgets directory ... That way, Github should be able to auto-detect that srdl2sv itself is licensed under the GPLv3 license.	2021-10-24 20:34:06 -07:00
Dennis Potter	d032e77ed8	Fix layout of GPLv3 license	2021-10-24 20:00:23 -07:00
Dennis	b6af2c154c	Update Git address to Github in README.md	2021-10-24 15:55:43 -07:00
Dennis	6719d21423	Fix simple_rw_reg.rdl so that the test passes ... The register was defined as a 64-bit register but the test was written under the assumption it's a 32-bit register. Furthermore, the hardware write-enable flag had to be set since all values would otherwise be overwritten immediately.	2021-10-24 15:43:44 -07:00
Dennis	c4964e0c57	Remove redundant example-file	2021-10-24 14:03:46 -07:00
Dennis	25b562ca65	Update warning and license description in README.md	2021-10-24 13:49:59 -07:00
Dennis	9ac58367ff	Add installation instructions to README.md	2021-10-24 13:22:09 -07:00
Dennis	7c55cfaa8e	Logger should always lazy evaluate variables	2021-10-24 12:36:17 -07:00
Dennis	49d1b598f0	Add setup.py to repository to install srdl2sv	2021-10-24 12:14:03 -07:00
Dennis	ec02290bbe	Move several methods to common Components ancestor ... For example, most methods relating to dimensions or genvars were moved to the Components class. Furthermore, some more care was taken of _ or __ prefixes for methods: - No method-prefix: Public variable that is will be called by non-related functions and methods. - _ method-prefix: Method will be called by class or class that inerhits class - __ method-prefix: Method will be called by class itself only	2021-10-24 00:07:59 -07:00

Dennis	d80224c43d	Do not generate seperate comparisons for cpu interface mux ... Rather, use the activate-signals that get generated anyway.	2021-10-19 23:33:59 -07:00

Dennis	9046dcf3e3	Description in regfile.yaml now says 'regfile' and not 'register'	2021-10-18 23:06:21 -07:00
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	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
