Otherwise, reading the GDS files from the OSU018 standard cell set into magic under SCN6M_DEEP.09 will generate large numbers of DRC errors. Note, however, that the LEF files from OSU018 do not specify metal extensions on the vias, and so stacked vias m1-m3 will cause minimum metal violations on metal2. The way around this is to specify via stacks = 1 to qrouter, so that every metal layer must route for at least 1 track width, which satisfies the minimum metal requirement.
* Added back parsing of option "buffer" for backwards-comptibilityTim Edwards2016-03-16
| | | | without breaking, although the option is non-functional.
* Fixed an incorrect parsing of one of the various possible versionTim Edwards2016-03-15
| | | | strings returned by yosys.
* Added "touch $synthlog" to the top of all the scripts afterTim Edwards2016-02-26
| | | | | synthesize.sh so that removing the log file does not generate an error message.
* Corrected a round-off error in the generation of .cel files byTim Edwards2016-02-18
| | | | | | | the decongest script. This would cause overlap of cells when cells have odd-numbered widths, leading to cell X positions that precess relative to the routing grid along the width of the layout.
* Corrected an error in vesta that would segfault on attempting toTim Edwards2016-02-16
| | | | | | | | | | | | deal with a latch that it thought was a flop. Also, modified blifFanout to give more relevant diagnostic information, such as units used for loads and latencies, and showing how "strength" relates to the specified maximum latency. Defaults for blifFanout made more realistic, especially for the default 0.35um technology, so that it doesn't constantly report that gates are too weak and try to change all gates to the maximum size. Option "-f" changed to "-I" ("I" for "Ignore") so that "-f" means do fanout buffering only, and "-L" means do load balancing only.
* Corrected handling of place2def so that it does not exit with anTim Edwards2016-02-12
| | | | | | | error if a route is given in the info file with a width or pitch of zero. Simultaneous change to qrouter behavior should not let such routes get into the info file, though. This check has been added to qflow as a precautionary measure only.
* Corrected installation and execution for local installations ofTim Edwards2016-01-09
| | | | | | yosys. Specifically, yosys calls yosys-abc, which if not in the standard search path, must be specified using the "-exe" switch to the "abc" command in yosys.

* Slight modification, as the unroute copy was being made beforeTim Edwards2015-11-22
| | | | the addspacers tool was run, leading to different file contents.
* Revised the way that the placement and router scripts handleTim Edwards2015-11-22
| | | | | | | | | output filenames. Placement now copies the .def solution to _unroute.def (previously done only at the end of the router script). The router script uses the _unroute.def file as input and does not overwrite it. The previous method allowed the _unroute.def file to become out of sync with the rest of the files.
* Added graywolf_options to list of variables defined inTim Edwards2015-11-20
| | | | | | project_vars.sh, so that specific arguments can be passed to graywolf. "-n" will disable graphics, allowing a fully graphics-free flow.
* Changed qflow behavior so that option "yosys_nodebug" is nowTim Edwards2015-11-13
| | | | | | "yosys_debug" and the non-debug behavior is the default (resulting in smaller layouts with fewer unconnected outputs that are useful only for debugging).
* Corrected a problem in the place2def.tcl script that was notTim Edwards2015-11-12
| | | | | | properly using the information from the info file to place pins on 1-of-N route tracks when the layer width and spacing rules require it.
* Corrected synthesis script, which had added the line necessary toTim Edwards2015-11-11
| | | | | process RTL in the verilog source, but only added it to the preliminary yosys script, not to the final one.
* Modified scripts so that the .cel file is generated as part ofTim Edwards2015-10-30
| | | | | | | | | | the placement script, not the synthesis script. The change is required due to the introduction of density planning, since the density affects the generation of the .cel file passed to graywolf for placement. If the .cel file is generated as part of the synthesis script, then if the density is modified, the flow has to be re-run from synthesis, not from placement. This update corrects the issue.
* Corrected one remaining error in the "decongest" density planningTim Edwards2015-10-29
| | | | | | script that does not handle the case of zero fill cells, and so was preventing densities above about 0.9 (one fill cell per standard cell).
* Extended the absolute path handling capability to all the majorTim Edwards2015-10-28
| | | | synthesis flow scripts.
* Modified the synthesis script so that the various files (lef,Tim Edwards2015-10-28
| | | | | techlef, gds, spice, liberty) can be specified as absolute paths and not have to be symbolic links from the tech directory.
* Corrected two errors with the decongestion routine. One errorTim Edwards2015-10-11
| | | | | | | | was an incorrect computation of the number of fill cells to make up the total density, resulting in fill cells being added even if the density was set to 1. The other was a round-off error resulting in an incorrect width value, which tends to cause bad route failures.
* Modified synthesis script to provide immediate output on theTim Edwards2015-10-04
| | | | | failure to find a verilog source file. Helps to catch and resolve gross errors faster.
* Added patch by Staf Verhaegen that passes a default script argumentTim Edwards2015-10-04
| | | | | | | | | | | to ABC that works much better than the default behavior, expanding the range of cells used (e.g., will use AOI and OAI cells instead of trying to shove everything into NAND/NOR logic). The practical impact appears to be an increase in circuit speed as well as routing efficiency. Added an additional hook from variable "abc_script" in project_vars.sh for manual control over this expression. 'set abc_script = ""' reverts to the original behavior.
* Corrected POLYGON handling of blif2cel.Tim Edwards2015-09-14
|
* Corrected density planning of "decongest" for situations whereTim Edwards2015-09-06
| | | | | | | | | | | the number of fill cells is less than the total number of cells, due to having only large filler cells in the standard cell set. Optimized "decongest" to make use of smaller fill cells if available, such that the fill cells will outnumber the standard cells, making the decongestion more evenly spread across the layout. Improved blif2cel.tcl so that cells that only use POLYGON for pins instead of RECT will not lose information in the .cel file.
* Noted that graywolf produces redundant net entries where it thinksTim Edwards2015-08-03
| | | | | | | that a route should go from a pin to both top and bottom of a cell, and that putting these redundant net entries into the DEF file output causes qrouter to report false failures. Rewrote the place2def script to avoid generating the redundant entries.
* Modified scripts such that all TCL scripts are annotated with theTim Edwards2015-06-03
| | | | correct path to "tclsh" on installation.
* Corrected Makefile.in in the src directory, or else vesta won'tTim Edwards2015-06-02
| | | | compile.
* Modified readliberty.c to ignore cells marked "dont_use".Tim Edwards2015-06-02
| | | | | | | | | Corrected synthesis script to no longer require a "gate.cfg" file to run blifFanout, since this has been deprecated (and is no longer in the set of installed files). Modified blifFanout to use the first buffer found in the liberty file, so details of the buffer cell do not need to be provided in the tech shell script (although they will be used, if passed to the program).
* Added a new option to "project_vars.sh" called "yosys_nodebug".Tim Edwards2015-05-29
| | | | | | | If set to 1, the yosys script uses "clean -purge" after the standard cell mapping. This removes all the buffers that are used to maintain internal signal names, resulting in a smaller but less easily debugged layout.
* Finally got around to updating the yosys script to use the defaultTim Edwards2015-05-29
| | | | "synth -top <rootname>" command, for yosys versions 0.5 and up.
