Z-scale Microarchitectural Implementation of RV32 ISA
License: Other
Hello zscale-developers,
could you provide some additional information, how to convert the scala sources to verilog? Adding the following main in zscale.scala results in Chisel. ParameterUndefinedException: Parameter CoreInstBits undefined.
object hello {
def main(args: Array[String]): Unit = {
chiselMain(ArrayString,
() => Module(new Zscale()))
}
Thanks a lot for your feedback.
Dear,
I want to build firmware to run on my fpga board. I use the script in the sw folder. There is an error as following.
riscv64-unknown-elf-gcc -m32 -static -Wa,-march=RVIM -std=gnu99 -O2 -fno-common -fno-builtin-printf -c -I./common -I./led -I./mbist ./common/trap.c -o trap.o
./common/trap.c: Assembler messages:
./common/trap.c:7: Error: Instruction csrw requires absolute expression
./common/trap.c:7: Error: Instruction csrw requires absolute expression
make: *** [trap.o] Error 1
How should I do to solve this error? Thank you!!!
I've pull the latest version of rep and trying to simulate 'mbist' example in ModelSim (see the attached fig).
I see that boot stage is working fine (initialization stack, register etc), then jump to 'init' symbol and ''main' entry point.
But I see problem on first access to dram (default map address 0x20000000). XBus doesn't transmit master's request on slave1 bus and everything stopped waiting positive signal HREADY on master1 port. I suppose problem somewhere in HASTISlaveMux_1.
Hi all,
to me it seems like in the HASTI implementation the very first transfer, when coming from idle, results in a wait state issued to the master even so the slave is actually ready. This is caused by the s1_grants register is deasserted because no requests and so no grants have been asserted before. In other words: The initial address phase gets stalled for one cycle (but will be latched according to AHB-Lite standard) because the previous but actually not real data phase is considered stalled (in.hreadyout is low) since no slave was selected. Can anyone confirm this behaviour?
(io.ins zipWithIndex) foreach { case (in, i) => {
val g1 = s1_grants(i)
in.hrdata := dgate(g1, io.out.hrdata)
in.hreadyout := io.out.hreadyout && g1
in.hresp := dgate(g1, io.out.hresp)
} }
Best,
Stephan
I have issues building zscale from scratch.
