Usage: When make emu, please use EMU_TRACE=1, EMU_TRACE=vcd or EMU_TRACE=VCD to dump waveform of vcd format, and use EMU_TRACE=fst or EMU_TRACE=FST to dump waveform of fst format. When use xiangshan.py, please add --trace to dump waveform of vcd format, and add --trace-fst to dump waveform of fst format.

Now we update data field (fwd data, uop) in load queue when load_s2 is valid. It will help to on lq wen fanout problem. State flags will be treated differently. They are still updated accurately according to loadIn.valid Co-authored-by: NWilliam Wang <zeweiwang@outlook.com>

* ldu: optimize dcache hitvec wiring In previous design, hitvec is generated in load s1, then send to dcache and lsu (rs) side separately. As dcache and lsu (rs side) is far in real chip, it caused severe wiring problem. Now we generate 2 hitvec in parallel: * hitvec 1 is generated near dcache. To generate that signal, paddr from dtlb is sent to dcache in load_s1 to geerate hitvec. The hitvec is then sent to dcache to generate data array read_way_en. * hitvec 2 is generated near lsu and rs in load_s2, tag read result from dcache, as well as coh_state, is sent to lsu in load_s1, then it is used to calcuate hitvec in load_s2. hitvec 2 is used to generate hit/miss signal used by lsu. It should fix the wiring problem caused by hitvec * ldu: opt loadViolationQuery.resp.ready timing An extra release addr register is added near lsu to speed up the generation of loadViolationQuery.resp.ready * l1tlb: replace NormalPage data module and add duplicate resp result data module: add BankedSyncDataMoudleWithDup data module: divided the data array into banks and read as Async, bypass write data. RegNext the data result * #banks. choose from the chosen data. duplicate: duplicate the chosen data and return to outside(tlb). tlb return (ppn+perm) * #DUP to outside (for load unit only) TODO: load unit use different tlb resp result to different module. one for lsq, one for dcache. * l1tlb: Fix wrong vidx_bypass logic after using duplicate data module We use BankedSyncDataMoudleWithDup instead of SyncDataModuleTemplate, whose write ports are not Vec.

To reduce fanout of in.valid and address, delay write by one clock cycle. Should be careful whether this brings bugs.
