Dennis	ed167c05de	Update AMBA 3 AHB Lite widget in examples with 33c92c8 (issue #9)	2021-10-30 23:35:38 -07:00
Dennis	33c92c8994	Closes #9: Error returns from regblock now actually get processed by AHB widget	2021-10-30 23:30:55 -07:00
Dennis	031e413d17	Fix test_simple_rw_reg.test_illegal_address so that it always recognizes issue #9 ... Before this fix, the bug would only pop up for addresses that were dividable by 4. Otherwise, the AMBA AHB 3 Lite widget would return an error response because of an illegal HSIZE/HADDR combination.	2021-10-30 23:27:14 -07:00
Dennis	7efe7c4cea	Update examples with changes from e46e51f and a148e8b ... The former commit implements fixes that were required for issue #8. The latter only updated the link to report bugs.	2021-10-30 19:38:43 -07:00
Dennis	a148e8bbd1	Update link in header to report bugs	2021-10-30 19:37:02 -07:00
Dennis	e46e51f3cf	Closes #8: Certain fields shall be implemented as wires or constants ... The software now detects whether a field shall be implemented with flops, with wires, or as a constant. Everything should now follow Table 12 and Section 9.5.1 of the SystemRDL 2.0 LRM.	2021-10-30 19:33:14 -07:00
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	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	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

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	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
